Turn Detection
Fluid speech interactivity for your custom Voice AI stack
Accurate end-of-turn detection is critical for natural, interactive dialogue between AI agents and users.
How turn detection works
Enable Natural Voice Interactions
Turn Detection helps your application identify conversational boundaries in real time. It uses voice activity cues and specialized models to distinguish between active speech, brief pauses, hesitations, and finished thoughts.
Natural interruptions
Prevents the agent from talking over the user
Rapid interactivity
Pinpoints exactly when the agent should respond
Reduced silence
Eliminates long timeouts for STT processing
Main Capabilities
Key features
Detect speech activity, interpret pauses, and trigger responses at the perfect moment in real-time Voice AI applications.
Voice activity detection (VAD)
Accurately detects the start and end of speech.
Turn boundary detection
Determines exactly when the speaker expects a response.
Pause and hesitation handling
Prevents brief silences from being mistaken for the end of a sentence.
Natural response timing
Triggers actions at more conversational, human-like intervals.
Low-latency operation
Runs in the Voximplant cloud for seamless, real-time integration.
Custom stack ready
Easily integrates into STT → LLM → TTS and other custom architectures.
Use Cases
Built for custom Voice AI scenarios
Turn Detection and VAD allow teams to add natural speech interactions to AI systems requiring precise control over timing, transcription, and pipeline design.
Voice-enable text-based agents
Add real-time speech interaction and telephony to agents originally designed for text-based chat.
Support text-only LLMs
Enhance agents originally designed for text chat by adding real-time speech and telephony features.
Extend language and dialect coverage
Use custom speech engines when default model support is insufficient for your target audience.
Improve accuracy for specialized speech
Handle industry-specific jargon, names, and pronunciation with tailored transcription and speech workflows.
