How Retell AI Works
Retell AI is designed to run on sophisticated language models that analyze and generate human voice interactions. The technology stack includes:
- Large Language Models: Natural language comprehension and generation.
- Voice Synthesis Algorithm: Generating ultra-realistic voices and emotions.
- ASR: Automatic Speech Recognition required for live transcription of spoken words and understanding of the same.
- Algorithms to handle Interruption: For handling conversation flow, there are algorithms built for interruptions that happen.
The process all begins with the ASR processing the textual input provided by a user. Next, the language model provides coherent and relevant contextual meaning to a meaningful response using the inputted data. In the end, these are synthesized into voice output with the use of the voice synthesis algorithms to ensure the interaction sounds natural and interesting.
