           How much data is required for professional voice fine-tuning?
         answer: |
-          You need trainig data of at least 300 lines of recordings (or approximately 30 minutes of speech) for professional voice fine-tuning. We recommend 2,000 lines of recordings (or approximately 2-3 hours of speech) to create a voice for production use. For the script selection criteria, see [Record custom voice samples](record-custom-voice-samples.md).
