Zonos is a local text-to-speech model for people who want to generate speech in a reference speaker's voice. It suits projects that need control over vocal delivery as well as voice matching.

openWakeWord is a wake word detection library for developers building voice apps that listen for a chosen word or phrase. It lets an application detect voice triggers on its own hardware.

Applio converts recordings and microphone input into another voice for musicians making AI covers, streamers and speech creators. You can choose community voice models or train a model from your own recordings.

Mattermost Agents adds AI assistants to a Mattermost workspace for teams working through long discussions and meeting recordings. Teams can use models on their own infrastructure or connect to a cloud provider.

ChatTTS Colab turns text into speech for people producing narration or scripts with different character voices. It builds on ChatTTS and provides a browser interface for comparing voices and generating long audio passages.

Google AI Edge Eloquent turns speech into edited text for people who prefer dictating notes and drafts to typing them. It uses on-device Gemma models to remove verbal filler and self-corrections.

Quill records meetings and creates transcripts on your Mac. It's for people who want to keep both the call audio and the resulting text on their own machine.

DoodleNote turns calls and rough jottings into meeting notes for people who want to keep recordings on their own computer. It captures both sides of a conversation in any meeting app without adding a bot to the participant list.

MeloTTS is a Python text-to-speech library for developers adding spoken output to their applications. It runs locally and can generate speech in real time on a CPU, so a dedicated GPU isn't required for inference.

Aiko turns recorded meetings, lectures and voice memos into text for people who want to keep their audio on their own device. It processes completed recordings rather than live speech and doesn't identify individual speakers.

Soul-of-Waifu is an AI companion app for creating characters and roleplaying with them. A character carries the same personality and memories between conversations, RPG campaigns and a desktop companion.
