Retell's Automatic Speech Recognition (ASR) engine has received a significant upgrade, enhancing transcription accuracy, intent detection, and call outcomes across seven widely used languages, while expanding support to include over 22 new languages, bringing the total to more than 50. This upgrade allows businesses to engage with a global audience more effectively, as the enhanced ASR engine improves real-time transcription accuracy, particularly in challenging telephonic environments affected by noise, connectivity issues, and various accents. The update introduces two transcription models: one optimized for speed and another for accuracy, significantly reducing Word Error Rates (WER) in European and Asian languages. This enhancement not only ensures clearer transcripts and better real-time understanding but also facilitates more precise intent recognition and a more seamless voice automation experience. As a result, businesses can expect higher call completion rates, smoother interactions, and substantial cost savings when transitioning to AI-powered voice agents.
