A free tier allows three transcriptions a day, while the paid Unlimited plan removes usage caps for a flat monthly fee.

Speech-to-speech platform for reliable voice agents.

Phonic is a platform for building production voice agents on its own end-to-end speech-to-speech models, rather than chaining separate speech-to-text, LLM, and text-to-speech stages. It targets sub-300ms latency for natural turn-taking and reliable tool calling, and bundles evaluation, session records, and real-time observability to surface failure points. Aimed at enterprises, it offers cloud API access plus containerized deployment in your own environment.

Voice AI agent platform for contact centers.

Ultra-low-latency text-to-speech that runs on-device.

Neuphonic is a voice-AI company building text-to-speech and voice cloning that run locally with very low latency. Its cloud API targets real-time voice agents, and in October 2025 it open-sourced NeuTTS Air, a 748M-parameter speech language model that runs on CPU via llama.cpp and clones a voice from a few seconds of audio. Aimed at private, offline, and voice-agent use cases.

Enterprise AI text-to-speech with voices licensed from real voice actors.

An enterprise-grade AI voice generator that produces realistic voiceovers from scripts. It offers 120+ voices across languages and accents — modeled on licensed recordings by real voice actors — plus a studio for script import and audio tuning, team workspaces, pronunciation libraries, Adobe integrations, and an API for products, LMS platforms, and IVRs.

Real-time voice AI: fast TTS and production phone agents.

An enterprise voice-AI platform built on deliberately small, fast speech models. Waves handles text-to-speech, voice cloning, and conversion in 30+ languages, while Atoms is a real-time voice-agent platform that plugs into business systems for support, lead qualification, and outbound calls. The company says it can generate 10 seconds of speech in about 100 milliseconds for sub-second voicebot responsiveness.
