The SDK uses a subscription-based event handling pattern:
const subscription = session.subscribe({
// Connection lifecycle
onConnected: async (args, context) => {
console.log("Connected:", args.connectionId);
},
onDisconnected: async (args, context) => {
console.log("Disconnected:", args.code, args.reason);
},
onError: async (args, context) => {
console.error("Error:", args.error.message);
},
// Session events
onSessionCreated: async (event, context) => {
console.log("Session created:", context.sessionId);
},
onSessionUpdated: async (event, context) => {
console.log("Session updated");
},
// Audio input events (VAD)
onInputAudioBufferSpeechStarted: async (event, context) => {
console.log("Speech started at:", event.audioStartMs);
},
onInputAudioBufferSpeechStopped: async (event, context) => {
console.log("Speech stopped at:", event.audioEndMs);
},
// Transcription events
onConversationItemInputAudioTranscriptionCompleted: async (event, context) => {
console.log("User said:", event.transcript);
},
onConversationItemInputAudioTranscriptionDelta: async (event, context) => {
process.stdout.write(event.delta);
},
// Response events
onResponseCreated: async (event, context) => {
console.log("Response started");
},
onResponseDone: async (event, context) => {
console.log("Response complete");
},
// Streaming text
onResponseTextDelta: async (event, context) => {
process.stdout.write(event.delta);
},
onResponseTextDone: async (event, context) => {
console.log("\n--- Text complete ---");
},
// Streaming audio
onResponseAudioDelta: async (event, context) => {
const audioData = event.delta;
playAudioChunk(audioData);
},
onResponseAudioDone: async (event, context) => {
console.log("Audio complete");
},
// Audio transcript (what assistant said)

},
// Function calling

await session.addConversationItem({
type: "function_call_output",
callId: event.callId,
output: JSON.stringify(result),
});
await session.sendEvent({ type: "response.create" });
}
},
// Catch-all for debugging
onServerEvent: async (event, context) => {
