Coqui

Coqui was a pioneering platform in the field of generative AI voice technology, renowned for its open-source contributions and the creation of highly realistic, emotive synthetic voices. Originating from Mozilla's deep learning research, Coqui empowered creators, developers, and enterprises to generate expressive human-like speech for a wide array of applications, from video game characters to corporate e-learning modules.

The platform was celebrated for its advanced voice cloning technology, which could replicate a voice with remarkable accuracy from just a few seconds of audio. This, combined with fine-grained control over vocal emotions and styles, made it a versatile tool for any project requiring high-quality voice work.

How to use Coqui

The platform offered a user-friendly workflow for both its web interface and developer tools:

1. Select a Voice: Users could choose from a vast library of pre-existing, high-quality AI voices or opt to create a new one.
2. Clone a Voice: To clone a voice, a user would upload a clean audio sample of at least 3 seconds. The AI would then process this sample to create a new, usable digital voice.
3. Generate Speech: Input the desired text into the editor. Select the desired voice (pre-made or cloned) and adjust parameters.
4. Direct the Performance: Utilize the 'Voice Director' feature to fine-tune the delivery, adjusting emotions (e.g., happy, sad, angry), pitch, pace, and emphasis to match the context.
5. Download and Integrate: Generate the audio and download it in a standard format like WAV or MP3. For developers, Coqui provided a robust API and an open-source library (🐸TTS) for seamless integration into applications, games, and services.

Pricing and Plans

Coqui previously operated on a freemium model, which included a free trial for users to explore its capabilities and generate a limited amount of audio. Paid plans were structured in tiers based on usage, such as the number of characters generated or voices cloned, catering to a wide range of users from individual creators to large enterprises. The open-source 🐸TTS library was always free for the developer community.
