Build voice agents that detect frustration, respond with empathy, and resolve issues on the first call. 48 emotion dimensions. Zero transcoding latency. Phone and web.
RealSpeak handles the voice infrastructure. You handle the business logic.
Define your agent's personality, system prompt, voice, and tools via the dashboard or API. Register the webhook where tool calls are sent.
Assign a Telnyx phone number to your agent. Inbound calls are answered automatically. Or embed the web widget for browser-based voice.
When the agent needs data, RealSpeak POSTs HMAC-signed tool calls to your webhook. Return results and the agent speaks them naturally.
Detect caller frustration before they escalate. Route angry callers to humans. Resolve routine issues autonomously.
Empathic patient intake. Triage calls by emotional urgency. Detect distress signals that text-based AI misses.
Read buying signals in real-time. Adapt pitch tone to caller mood. Know when to push and when to listen.
Real-time emotional assessment. Route high-risk callers immediately. Provide warm handoffs with context.
Full REST API + WebSocket. Create agents, manage tools, query call history.
