Twilio has announced that voice recordings are now recorded and stored in dual-channel by default at no additional cost starting May 25th for new accounts, and being rolled out for all existing accounts. This change enables better speaker accuracy in call recordings, as each participant's audio is stored in a separate channel. Dual-channel recordings can be processed to improve the accuracy of transcriptions and sentiment analysis, making it easier for organizations to analyze customer conversations and identify areas for improvement. The new feature allows users to download files in mono or dual-channel without requiring any changes to their Twilio application, and provides greater flexibility and scalability for call recording and transcription needs.
