Play.ht
Neural text to speech and voice cloning platform with premium voices multi language support timeline editing and a low latency API for apps and games.
Overview
ht provides realistic speech generation and cloning tools for creators and developers. Users can pick from premium voices across many languages and control pacing, pauses, emphasis and pronunciation through SSML and a timeline editor that supports multi speaker mixes. Voice cloning allows creation of custom voices with appropriate rights and consent, suitable for branded content and character work when policies permit.
For developers, a low latency API streams audio for assistants, IVR and real time experiences, while batch synthesis supports audiobooks, courses and localization at scale. Asset management keeps projects organized with versioning and sharable previews so stakeholders can approve takes quickly. Commercial licenses and usage logs help teams stay compliant.
ht aims to reduce the distance between a script and production ready audio while giving enough control to sound natural, not robotic.
