About Paraformer Realtime v2

Streams audio in, transcripts out
Unusually wide Chinese regional dialect coverage
Language_hints parameter guides detection

Paraformer-Realtime-v2 is Alibaba Cloud's earlier-generation real-time speech recognition model, streaming audio in and transcripts out over a bidirectional connection.

  • It recognizes Chinese Mandarin along with an unusually wide set of regional dialects (Cantonese, Wu, Hokkien, Sichuan, and more) plus English, Japanese, Korean, German, French, and Russian, and supports a language_hints parameter for guiding detection.
  • Alibaba's docs now recommend Fun-ASR or Qwen-ASR for new projects, positioning this model for existing integrations.
  • Synthorai continues to serve it via the OpenAI-compatible endpoint.
