voice.answer()
The answer() method is used in real-time voice providers to trigger the AI to generate a response. This method is particularly useful in speech-to-speech conversations where you need to explicitly signal the AI to respond after receiving user input.
Usage exampleDirect link to Usage example
import { OpenAIRealtimeVoice } from '@mastra/voice-openai-realtime'
import { getMicrophoneStream } from '@mastra/node-audio'
import Speaker from '@mastra/node-speaker'
const speaker = new Speaker({
sampleRate: 24100, // Audio sample rate in Hz - standard for high-quality audio on MacBook Pro
channels: 1, // Mono audio output (as opposed to stereo which would be 2)
bitDepth: 16, // Bit depth for audio quality - CD quality standard (16-bit resolution)
})
// Initialize a real-time voice provider
const voice = new OpenAIRealtimeVoice({
realtimeConfig: {
model: 'gpt-5.1',
apiKey: process.env.OPENAI_API_KEY,
},
speaker: 'alloy', // Default voice
})
// Connect to the real-time service
await voice.connect()
// Register event listener for responses
voice.on('speaker', stream => {
// Handle audio response
stream.pipe(speaker)
})
// Send user audio input
const microphoneStream = getMicrophoneStream()
await voice.send(microphoneStream)
// Trigger the AI to respond
await voice.answer()

options?:
Record<string, unknown>
Provider-specific options for the response
Return valueDirect link to Return value
Returns a Promise<void> that resolves when the response has been triggered.
NotesDirect link to Notes
- This method is only implemented by real-time voice providers that support speech-to-speech capabilities
- If called on a voice provider that doesn't support this functionality, it will log a warning and resolve immediately
- The response audio will typically be emitted through the 'speaking' event rather than returned directly
- For providers that support it, you can use this method to send a specific response instead of having the AI generate one
- This method is commonly used in conjunction with
send()to create a conversational flow
