Best Practices
Use MP3 Format
MP3 files are significantly smaller than WAV files, reducing storage costs and bandwidth usage. Use MP3 unless you specifically need uncompressed audio.
Set Reasonable Time Limits
Configure appropriate time limits to prevent unexpectedly large files and control costs. Default is 60 seconds, adjust based on your use case.
Transcription Limitations
Transcription is only available for English calls with duration between 500ms and 4 hours, and file size under 2GB. Factor these limits into your application design.
Use Stereo for Multi-Party
For calls with multiple participants, use stereo recording to separate speakers into different channels for easier analysis and transcription.
Legal Compliance
Always comply with local laws regarding call recording consent. Many jurisdictions require informing all parties that the call is being recorded.
