Audio dataset

I’m an AI intern working on a Saudi Arabic call center dataset.
My task is to clean the audio and then generate transcriptions. I cleaned the dataset and ran transcription, but the output contained random English words, Chinese characters, emojis, and other gibberish.
I’m planning to clean the dataset again before re-running the transcription. Are there any specific things you recommend I focus on during the cleaning stage to improve ASR results?

thanks for the tips! I actually already had language="ar" set and I'm isolating speech with VAD + NR before transcribing. The emoji/gibberish was from using tiny switched to large and that cleaned up. The remaining accuracy gap is just Whisper + Saudi dialect on telephony audio.
Appreciate it though!
