| <p style="margin-bottom: 10px; font-size: 94%"> | |
| Whisper is a general-purpose speech recognition model released by OpenAI that can perform multilingual speech recognition as well as speech translation and language identification. Combined with an emotion detection model,this allows for detecting emotion directly from speech in multiple languages and can potentially be used to analyze sentiment from customer calls. It could also be used to transcribe and detect different emotions to enable a data-driven analysis for psychotherapy. | |
