ProsodyAI

ProsodyAI is an all-in-one AI voice generation and video production platform that gives creators, marketers, businesses and developers access to two leading neural text-to-speech engines — OpenAI TTS and Google Gemini TTS — from a single account, a single voice list and a single quota. Positioned as "AI text to speech voice with soul", it stands out by letting users direct delivery in plain language: instead of choosing from a rigid preset emotion menu, you simply describe the read you want ("warm and unhurried", "brisk and factual", "a hushed aside") and the engine performs it. Between the two engines the platform covers 59 languages — OpenAI TTS handles 57, while Google Gemini TTS adds regional voices such as Indonesian, Vietnamese, Thai, Ukrainian, Bengali and Tamil. Beyond pure speech synthesis, ProsodyAI bundles a Video Studio, AI video generation, up to 30-second talking-video avatars, and an AI Ad Generator with fifteen ready-made templates that turn a single product photo into a finished video ad. Dedicated use-case tracks serve YouTube creators, podcasters, e-learning producers and companies building IVR call-centre menus. Core features include batch rendering, MP3/WAV/FLAC export, a mastering filter, usage analytics, priority queues on paid plans, and a REST API with webhooks for developers — with the same request shape across both engines so switching voices never means rewriting code. The user experience is web-first with companion iOS and Android apps, a free trial of 1,000 premium characters and no credit card required. Technically, the service runs over TLS, stores passwords and API keys only as hashes, processes personal data under GDPR and KVKK, and targets sub-3-second latency for short texts with automatic parallel chunking for longer content.
