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.

TTS Voice Wizard is a software that allows users to transform their speech into text and then reconvert it to speech using Microsoft Azure Voice Recognition and TTS. Additionally, it transmits OSC messages to VRChat to exhibit text on an avatar. The software offers numerous customization features, including over 100 voice options, support for more than 20 languages, and the capability to display song titles, artists, and progress above the user.

Speech Studio offers a suite of tools designed to incorporate Azure Cognitive Services Speech capabilities into applications. It allows users to design projects without any coding, offering features such as live speech-to-text, tailored speech recognition models, pronunciation evaluation, voice gallery, custom voice creation, audio content generation, bespoke keywords, and personalized commands.
