Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

v0.6.25

Ollama Version (if applicable)

No response

Operating System

Debian 12

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

User can set the the ISO 639-1 language Whisper uses for STT.
Open-webui will include the language in the OpenAI request.

Actual Behavior

Since v0.6.23 Open-webui always request "en" instead of the language specified in user settings.
Using the environment configuration WHISPER_LANGUAGE to change the language, for example to “de,” works.

Steps to Reproduce

  1. Login to Open-webui
  2. Settings
  3. Audio
  4. Language : de

I have the same issue. All stt generates English text. If I start with a Japanese voice I end up with an English translation in text instead of the actual Japanese text.
