voice agent platform

definition

A voice agent platform is the managed runtime plus the tooling a team needs to put voice agents into production and keep them healthy. The runtime holds the conversation. The platform adds everything around it: workflow design, testing, observability, access control, and the billing model that makes all of it predictable.

An API gives you the runtime. A no-code builder gives you a bot. A platform gives you a fleet you can operate, audit, and scale. SpeechifyAI is the third one.

capabilities

Six things separate a platform from a toolkit. Deterministic workflows for the steps that must follow a script. Simulated callers that catch regressions before a real customer does. Live operations APIs for watching and steering calls as they happen. Per-action RBAC so the right people hold the right controls. SOC 2 Type II with no training on your data. And forward-deployed engineers on Enterprise when you want a team in the room.

testing-and-evals

A voice agent breaks in ways a unit test never sees. Callers talk over the agent. They go quiet. They ask the same thing two different ways in three seconds. SpeechifyAI ships simulated callers as a first-class feature: reply tests for single turns, tool tests for your API calls, and full-conversation tests for whole scenarios, all run on the real worker runtime and judged server-side.

operations

Once agents are live, the live operations APIs keep you in the loop. Stream transcripts in real time. Take over a call and hand it to a human. Query analytics and save dashboards. Every one of these is gated by per-action RBAC, so listening in and intervening are separate, governed permissions.

pricing

One all-in rate covers the LLM, the speech stack, the workflow runtime, and telephony: $0.07/min on Pro, from $0.06/min on Enterprise. Compliance features are in the platform fee, not bolted on as line items. See the pricing page for the full table.
