Code-first or visual
Define agents in TypeScript with the SDK or use the browser flow builder. Both surfaces resolve to the same platform contracts.
VoiceLayer platform
A production platform for AI phone agents
VoiceLayer combines a TypeScript SDK and visual builder with telephony, structured workflows, memory, provider choice, guardrails, observability, and stateful human handoff. Teams ship a governed business process instead of assembling an audio demo.
Structured processes
Capture typed fields, branch deterministically, and gate tool actions without hiding business logic inside a prompt.
Live context and memory
Load caller and tenant context before the first response, with explicit scope and retention controls.
Provider choice
Run speech-to-text, language models, text-to-speech, and carriers behind swappable provider contracts.
Guarded execution
Apply input, prompt, output, and action controls across the runtime instead of relying on prompt instructions alone.
Human handoff
Transfer a call with transcript, intent, and workflow state so the caller does not have to start over.
Testing and observability
Test flows before launch, inspect call events, review transcripts, and keep post-call work off the live audio path.
Usage-based pricing
Start with a $10 credit, then pay a $0.05 platform fee per voice minute plus providers passed through at cost.
How a call runs
- 1. Resolve and prepareRoute the number to an agent and load caller, tenant, process, and policy context.
- 2. Converse and executeStream speech through the governed runtime while structured workflows and tools move the task forward.
- 3. Complete or escalateFinish the process automatically or hand the live call to a person with its state preserved.
Common questions
What is an AI phone agent platform?
An AI phone agent platform combines telephony, speech recognition, language-model reasoning, speech synthesis, workflow execution, tools, monitoring, and human escalation so an automated agent can complete real phone calls safely.
What is VoiceLayer?
VoiceLayer is a production platform for AI phone agents. Teams define an agent in TypeScript or a visual builder, while VoiceLayer operates the governed speech, model, workflow, telephony, memory, and post-call runtime.
Can developers bring their own model and voice providers?
Yes. Speech-to-text, language-model, text-to-speech, and carrier integrations sit behind provider contracts. Teams can use platform-managed providers or bring supported provider keys.
Does VoiceLayer support human handoff?
Yes. Handoff is a platform primitive designed to transfer the live call together with its transcript, detected intent, and workflow state.
