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.

January 2026 Self-Hosted Release: Update Recommendation

In Deepgram’s January 2026 self-hosted release (release-260115), we added new functionality to improve TTS response times from our API and Engine containers.

Due to this product change, the January 2026 self-hosted release is not backwards-compatible with previous releases when used to serve TTS traffic. It is a breaking change in how the API and Engine containers communicate with each other. To avoid any downtime in your self-hosted deployment, the updated version of the Engine node (3.107.0-1) must be running in advance of the updated version of the API node (1.176.0) serving requests. Note that the new version of the Engine (3.107.0-1) is compatible with previous versions of the API, so the Engine container must be deployed before the API container. The blue-green deployment strategy is one possible deployment strategy, but there are others that satisfy the requirement that the Engine container is deployed first. This is only applicable for deployments serving TTS traffic. The breaking change is not relevant to deployments serving STT traffic.

The License Proxy node is not impacted by breaking changes, but in the context of a complete Deepgram self-hosted deployment, it is most cohesive to also include the update to the License Proxy node (1.9.2) in the blue-green deployment.

This Release Contains The Following Changes

  • Improves Transcription of “Um” in Portuguese — Monolingual Portuguese STT now transcribes “um” (meaning “one”) as a non-filler word, and “um” is included in Portuguese transcripts, even when the filler_words feature is disabled.
  • General Improvements — Keeps our software up-to-date
