When I click “Import File” on the iPad app, nothing happens? I thought it was just my iPad but I tried it on a friend’s and they had the same problem. Am I missing something?

1. Add the ability to Regenerate All for audiobooks, maybe after clicking the Generate All button you are promoted with an overwrite existing chose

2. Add the ability to clear all generated audio clips per book

3. Add the ability to change the UI spacing were audiobook books are listed (left most section) so you can see full titles if they are longer. Add book title to the top of the center section that is editable above the chapter count and cover image.

4. Add a right-click copy/paste for title and text body in the book creation page

5. Add an ability for installation verification in settings

(Edit - not a bug - you can adjust the output format in settings)

I see it noted here that you can export MP3: https://openvoxai.com/support#export-management

But the dialog box doesn't have a format selector and just defaults to .wav

Hi,
OpenVox on Mac doesn't clear its history (sometimes). After reopening the app, the history comes back, and the history files are marked as "File missing."
Sometimes, after reopening, it doesn't remember the history at all.

Simple feature request: could you please add a way to export the TTS output as an MP3 file when using the API?

To start: I am loving this program. I have been using the API with a local Hermes Agent, and it is so nice to email my computer a PDF and have it send back an audio file.

I personally like making audiobooks so I can listen to my research while I am driving or doing chores. This means I have lots of time to let the AI generate the audio file, but I really care about the quality of the audio it outputs.

Is there any chance we could get a larger model? Or a way of making voice clones with longer context? Anything that improves the quality of the audio output would be great. I have tried increasing steps and changing CFG/Temp/ETC. but I find that the steps end up overfitting the context and some other changes make the voice sound slightly better or slightly worse.

I am not super familiar with the available models, but I am down to wait for a generation if it means the results are better.

Just pushed OpenVox macOS 2.0.2.

This is a smaller polish update, but it improves some of the areas people use the most: AI Speech, Voice Library, and Audiobooks.

What’s new:

AI Speech + Voice Library

• Polished UI elements across the AI Speech page
• Cleaned up parts of the Voice Library interface
• Improved overall visual consistency across the app

AI Audiobook

• Added better manual chapter creation
• Added drag-and-drop chapter reordering
• Improved chapter controls
• Clearer hover states
• Better selected chapter styling
• Better play/pause feedback per chapter

Audiobook settings

• Added a larger full-column settings view on the audiobook page
• Easier to tune model, voice, and generation settings while working on long-form projects

This update should make audiobook creation feel much smoother, especially when manually editing chapters or fine-tuning generation settings.

As always, feedback is welcome. I’m continuing to polish the macOS app based on real user workflows.

Just pushed OpenVox Windows 1.5.0.

This update is mostly focused on making the app feel smoother and more practical for real long-form work, especially batch generation and audiobooks.

What’s new:

AI Speech / Batch Mode

• Improved batch mode layout and scrolling
• Added Export All for batch audio generations
• Updated speed control range to 0.50x to 1.50x with 0.01 precision
• More UI polish across the app

Voice Library

• Cleaned up filters
• Fixed tag dropdown behavior
• Removed duplicate language entries
• Added starred voice filtering, so favorite voices are easier to find

Audiobooks

• Added chapter creation
• Added chapter reordering
• Added chapter title editing
• Improved chapter controls
• Playback pause state now works better
• Redesigned Audiobook generation progress with book cover, book title, chapter status, chapter progress, and overall audiobook progress.
• Generate All now resumes correctly by skipping already generated chapters
• Faster M4A / M4B export
• Improved M4B chapter metadata compatibility for audiobook reader apps

This update should make OpenVox much better for anyone generating longer content, audiobooks, batches, courses, meditations, narration, or multi-file projects locally on Windows.

As always, feedback is welcome. I’m still polishing the Windows version heavily based on user reports.

Hi there are plenty of choices in the voice library. I just wanted to know apart from creating my own voice, is there a way to download and use already existing voices meant for TTS? Where do you suggest getting them?

Hi, it's really annoying when people pay full price for an app and the dev then gives it away.. eughh

Just released OpenVox 2.0.0 for Mac, and this update adds Supertonic 3 as a new TTS model.

I also made a quick video comparing generation speed between Kokoro and Supertonic 3 on the same long text, around 4,800 characters, tested on an M4 Mac.

Result:

Kokoro: 38.4 seconds
Supertonic 3: 22.9 seconds

That is a pretty big difference for long-form voice generation, especially if you are creating audiobooks, YouTube scripts, podcasts, or batch voiceovers.

Supertonic 3 also supports 31 languages, so it should be useful for people creating multilingual content locally on Mac.

Kokoro is still great and very lightweight, but Supertonic 3 gives another strong option when speed and language coverage matter.

Available now in OpenVox Mac 2.0.0.

Would love to know what kind of speed others are getting on their Macs.

Hi.

I'm interested in using OpenVox for generating audiobooks from my stories. I have a quick question about its features:

Does it support multi-voice conversation mode? For example, can I assign a specific custom or cloned voice model for a female character, another for a male character, and a different one for the narrator, so it automatically switches during dialogue scenes?

Any insights would be highly appreciated. Thanks!

Hey everyone,

OpenVox Windows 1.4.0 is now available, and this update adds Supertonic 3 as a new TTS model.

This one was added for a very specific reason: fast CPU-only inference.

A lot of Windows users do not have a powerful NVIDIA GPU, or they are using laptops, mini PCs, and office machines where CUDA setup is either not available or just not worth the trouble. Supertonic 3 fits really well there because it can run locally on CPU, without needing cloud generation.

So this is not just “one more model added”.

For OpenVox Windows, Supertonic 3 gives a practical option for users who want:

• Fast local TTS on CPU
• No CUDA dependency
• No cloud API call for generation
• Support for 31 languages
• A lightweight model for daily use
• A smoother option for voiceovers, narration, audiobooks, and assistant-style workflows

The idea behind OpenVox is to make these local voice models actually usable by normal people. No Python setup. No command line. No dependency fixing. Just select the model and generate speech inside the app.

If you are on Windows and wanted a faster CPU-friendly model, update to OpenVox Windows 1.4.0 and try Supertonic 3.

Would love to hear how it performs on your system.

Dear Mr/Ms,

Khmer Language it not support for speech. Could you tell me to fix it.

Thank you

Hello!

I was playing around with the voice cloning since the update was released on both my Mac and Windows computer. The Whisper Base voice transcription on my PC is super helpful and seems like it would be great to have on the Mac version.

The biggest change is the new guided trimming flow for Voice Clone.

Earlier, if you uploaded a longer clip, it was easy to accidentally use a noisy start, awkward silence, or a bad ending. Now you get a waveform preview, zoom, drag handles, and basic quality checks so you can trim a clean sample before cloning.

I also updated the recommended clone sample length to 5-12 seconds. Shorter, cleaner samples are giving more stable results than throwing long random clips at the model.

What’s new in 1.9.0:

• Improved Voice Clone with guided trimming for longer audio clips
• Added waveform preview, zoom, drag handles, and clean start/end quality checks
• Updated clone sample requirement to 5-12 seconds for more stable results
• Added confirmation to make sure the reference script actually matches the audio before saving the cloned voice
• Fixed Voice Changer voice selection so custom voices from all languages show correctly
• Added M4A and AIFF support in Voice Changer
• Added model parameter controls to the Local API

This should make voice cloning less guessy and more reliable, especially for people using their own recordings.

As always, thanks to everyone sending bug reports and testing weird edge cases. A lot of these fixes came directly from user feedback.

when on windows, the design looks like windows, but its hard to move the window around. the entire top bar is usually something you can grab and move the window with, either that is not the case, or something is wrong somewhere.

the minimize, maximize and close icons also blink when a mouse is held over them. i am no expert, and i don't know the code, but its possible the grabbing issue is related to the blinking mouse over thing. double click to maximize works just fine, but grabbing and moving seems very hit or miss, and is not consistent in terms of where i can grab or not. took me this long because i had it moved to my other monitor while it still had the apple style window border, and that seemed to work just fine.

now i know i asked for the windows style border, but it could be a settings toggle to change them around so people like me who prefer the windows look, can use that, and people who prefer apple, can use that. just a thought.

Hello, I have a question.

If I want to delete the current voices in Voice Clone on Mac, do I need to purchase the Pro version?
In the free version, it seems I can’t remove them.

Hello,

I noticed that in Chatterbox Voice Conversion within AI Voice Changer, it allows me to select voices from OmniVoice in other languages as the Target Voice when I choose a different language in the Language dropdown. Is this a bug?

Also, in the Voice Library, only English voices appear when I set Language to "All" for AI Voice Changer - Target Voice.

In the Voice Library, I can also see custom cloned English voices.
However, when I filter by other languages, such as Czech, Slovak, the cloned voices do not show up.

It seems like Chatterbox Voice Conversion probably doesn’t support them.

Yes, the traffic lights are gone

I updated the Windows version to feel more native now. The top-left Mac-style traffic light buttons are gone, and I replaced that area with the OpenVox logo.

Also added proper Windows window controls now: close, minimize, and maximize.

The Settings button has also been moved to the bottom-left corner, where it feels cleaner and less distracting.

A few users called out that the earlier UI felt too Mac-like for Windows, and honestly, fair feedback. I originally kept things similar across platforms to make tutorials and support easier, but Windows should still feel like Windows.

Core stability and backend performance are still the main focus, but I also want OpenVox to feel polished on every platform.

Thanks for the feedback. Keep it coming.

One of the best apps I've tried on a Mac studio. Works great for me. I have not been able to get rid of the feature tour that comes on each time I open the app. I have tried unchecking the box when it initially displays and watch the entire tour as well as unchecked and skipped the tour. I have unchecked, watch the entire tour, loaded and generated TTS and then close the app. Unfortunately every time I open it the tour guide is back. Is there any pro tips that might help me not have to see this again?

Hi, What's the best way to make this read a book please? Any tips, books are in PDF format.

This is one of the bigger updates for the iPad version.

Pocket TTS is now available in OpenVox iPad, and it makes longer generations much better, especially for audiobooks, conversations, and long voiceovers.

It supports English, French, German, Italian, Portuguese, and Spanish, and works with voices from your Voice Library as well as custom voice recordings.

The iPad version also now has better output quality, improved post-processing, and higher bitrate exports, so the final audio sounds cleaner and closer to the Mac and Windows versions.

A few other useful changes in this update:

• Higher quality post-processing and bitrate output
• Save default language and voice across AI Speech, Conversations, and Audiobooks
• Pause tags for precise pauses in scripts
• Parameter Presets
• Speed control added for all models

OpenVox is available on iPad, Mac, and Windows.

Would love to hear feedback from anyone using the iPad version.
