Text-To-Speech

SpeechGen assists creators in converting scripts and subtitles into audio for videos, lessons, and presentations. The browser-based editor includes over 5,000 voices spanning 150 languages, with voice samples provided to aid in selecting a speaker. You can allocate different voices to specific sections of the script, adjust the delivery and pauses using SSML, and incorporate background music. The service also offers tools for converting subtitles to audio and provides a REST API for integrating speech generation with other workflows. The generated audio can be downloaded in MP3, WAV, or FLAC formats. Pricing starts at $4.99 with one-time, pay-as-you-go credit packs. A free trial is available. The amount of credits used depends on the length of the text and the chosen voice quality.

KittenTTS is an ultra-lightweight open-source text-to-speech model that converts written text into natural-sounding speech with impressive quality, all while requiring minimal computational resources. Unlike most speech conversion AI models that demand powerful hardware, KittenTTS operates efficiently on almost any device, including older computers, Raspberry Pi, and even browsers, thanks to its tiny size of 25 MB and design with 15 million parameters. This AI model provides several realistic voices in real-time without needing an internet connection or GPUs, making it ideal for developers creating privacy-focused applications, edge computing projects, accessibility tools, or any scenarios where resource efficiency is vital. Combining high output quality, incredible speed on CPU-only systems, and an open-source Apache 2.0 license, KittenTTS represents a breakthrough in AI-powered voice conversion where larger models simply cannot function.
