A tutorial demonstrating how the ADK (Agent Development Kit) automatically configures inputAudioTranscription and outputAudioTranscription for single-agent live scenarios. This tutorial showcases that the feature now works for all live scenarios, not just multi-agent scenarios.

This tutorial verifies the feature change in Runner.java that enables automatic transcription configuration for all live scenarios:

Before: Only multi-agent scenarios got automatic transcription

if (liveRequestQueue.isPresent() && !this.agent.subAgents().isEmpty())

After: All live scenarios (including single-agent) get automatic transcription

if (liveRequestQueue.isPresent())

When you use this single-agent with live audio, the ADK automatically configures:

• inputAudioTranscription - Transcribes user speech to text
• outputAudioTranscription - Transcribes agent speech to text

export GOOGLE_GENAI_API_KEY={YOUR-KEY}

cd tutorials/live-audio-single-agent

Start the server:

mvn exec:java

This starts the ADK web server with a single weather agent (weather_agent) that supports live audio using the gemini-2.0-flash-live-001 model.

Once running, you can interact with the agent through:

• Web interface: http://localhost:8080
• Agent name: weather_agent
• Try asking: "What's the weather in Tokyo?" or "How's the weather in New York?"

1. Open the web interface at http://localhost:8080
2. Enable your microphone
3. Speak to the agent: "What's the weather in Tokyo?"
4. The agent will:
   • Automatically transcribe your speech to text (inputAudioTranscription)
   • Process the request and call the getWeather tool
   • Respond with audio (automatically transcribed via outputAudioTranscription)
