What It Does
AI Voice Bridge runs locally on your computer.
It adds a small floating control to supported AI chat sites in Chrome. You can dictate a prompt locally, insert it into the chat box, send it manually, or use a simple final phrase command to send it automatically.
When the AI responds, AI Voice Bridge can read the response aloud using your computer’s local system voice.
It is not trying to replace ChatGPT, Claude, DeepSeek, or Gemini.
It adds a local voice bridge on top of the normal text chat experience.
Voice Command Auto-Send
AI Voice Bridge supports a simple voice command for sending messages.
If your dictation ends with “send message” or “send a message”, the bridge removes that final command phrase and submits the remaining prompt automatically.
Example:
You say: Explain this in one paragraph send message
The AI site receives: Explain this in one paragraph
The command only triggers when the send phrase is the final phrase. Saying something like “send message to the client” will not trigger auto-send.
Controls
AI Voice Bridge keeps the controls simple.
- Click the Mic button to start recording
- The Mic button turns red while recording
- Click the Mic button again to stop recording and transcribe
- Press Enter while recording to stop and transcribe
- Windows dictation hotkey: Ctrl + Shift + V
- Mac dictation hotkey: Cmd + Shift + V
- Click Repeat to replay the latest captured AI response
- Click Stop to stop current local readback
- Press Esc inside the AI site tab to stop local readback
Why We Built It
Native voice modes can be convenient, but they come with tradeoffs.
The biggest one is control. With native voice, your audio is routed through the platform’s voice system. That means the voice feature, transcription behavior, retention rules, usage limits, and overall experience are controlled by the platform.
For example, OpenAI’s own Voice Dictation FAQ says audio from dictation is retained for as long as the chat remains in your chat history. Its Voice Mode FAQ says audio and video clips from voice chats are retained for 30 days.
That may be fine for some people, but we wanted another option.
With AI Voice Bridge, dictation audio is sent only to the local server running on your own computer. The supported AI platform receives the final text prompt only when you choose to send it.
Voice features can also change. They can be limited, paywalled, removed, tuned differently, or made less useful over time. The voice experience you like today may not be the same one you get tomorrow.
There is also a practical difference between using a platform’s native voice mode and using the normal text version of the AI. Native voice can feel different from the regular chat experience. Sometimes it does not feel like you are using the same AI workflow.
AI Voice Bridge takes a simpler approach.
- Use the normal AI chat in Chrome
- Dictate locally on your own machine
- Send only the final text prompt when you choose to send it
- Let the AI answer in text
- Let your own computer read the answer out loud locally
That’s the point. Less platform control. More user control.
How It Works
AI Voice Bridge runs a small local server on your computer at 127.0.0.1:5055.
The Chrome extension talks to that local server.
When you dictate, your microphone audio is sent to the local server on your own machine, transcribed locally with Whisper, and inserted into the AI chat box as text.
When the AI responds, the bridge captures the response text and reads it aloud through your computer’s local system voice.
The supported AI platform receives the same thing it normally receives: a text prompt.
Raw microphone audio is not sent to ChatGPT, Claude, DeepSeek, or Gemini by AI Voice Bridge.
Why It Matters
This is not trying to replace the AI platforms.
It gives you a local voice layer for the AI tools you already use.
That means you can keep using normal ChatGPT, Claude, DeepSeek, and Gemini in Chrome while keeping voice interaction simple, local, and under your control.
Native voice mode is convenience. AI Voice Bridge is control, privacy, and consistency.
AI Voice Bridge v3.0 is available now for both Windows and Mac.
