Nova-3 Multilingual Model Update

🌍 Nova-3 Multilingual Improvements

We’ve released an updated Nova-3 multilingual model, delivering accuracy improvements across supported languages, with the largest gains in code-switching scenarios.

This update focuses on improving real-world multilingual speech recognition, especially for inputs that mix languages within a single utterance or conversation.

Key improvements include:

  • Lower Word Error Rate (WER) across both batch and streaming inference for all languages supported by the multilingual model
  • Significantly improved code-switching handling, reducing word drops when languages are mixed

These improvements help developers build more reliable, natural multilingual voice experiences without changing APIs or configuration.
