SenseVoiceSmall is a speech foundation model that supports multiple speech understanding capabilities, including automatic speech recognition (ASR), spoken language recognition (LID), speech emotion recognition (SER), and audio event detection (AED). After training for more than 400,000 hours on data, the model supports more than 50 languages and has a recognition performance that surpasses the Whisper model. The SenseVoiceSmall model, which is a small model, uses a non-autoregressive end-to-end framework with extremely low inference latency and handles a 10-second audio in only 70 milliseconds, which is 15 times faster than Whisper-Large. In addition, SenseVoice also provides convenient fine-tuning scripts and strategies, supports multi-concurrency request service deployment pipelines, and the client languages include Python, C++, HTML, Java, and C#.
