Vocal Bridge

Vocal Bridge: Voice for your agents and apps

Vocal Bridge is a developer platform designed to integrate real-time voice capabilities into applications, existing AI agents, and large language models. The platform provides a unified voice layer that handles bidirectional data channels, text-to-speech, and outbound calling, allowing developers to build voice-first experiences without managing complex WebRTC infrastructure.

Key Features

• Bidirectional Voice for Apps: Embeds real-time voice experiences directly into user interfaces using a single WebRTC data channel for synchronized agent and app interactions.
• Drop-in SDKs: Offers React, JavaScript, and Flutter SDKs to integrate voice components with minimal code and built-in live transcripts.
• Voice for Existing Agents: Adds a voice layer on top of any existing text-based AI agent or LLM, such as Claude, GPT, or Gemini, using just two lines of code.
• Streaming-Aware TTS: Automatically handles conversational nuances like filler words, user barge-ins, and hand-offs without altering the underlying reasoning layer.
• Voice as a Tool: Enables tool-using LLMs to dial out, conduct real phone calls, and stream transcripts back into the context window.
• Managed Outbound Calling: Provides fully managed outbound call infrastructure, including provisioned numbers, SIP trunking, and TCPA-aware compliance.

Use Cases

• Voice-first financial assistants replacing traditional forms and dashboards
• Healthcare applications for clinical trial matching and patient prep guidance
• Productivity tools allowing executives to navigate complex reports via voice
• Research platforms enabling users to query and summarize documents aloud
