Quick answers
Frequently asked questions
1What are the usage limits for text-to-speech generation on the web platform?⌄
Free tier usage typically includes a monthly character limit for synthesis, often sufficient for testing and small projects. Commercial use or higher volume requirements necessitate a subscription plan, which unlocks increased character quotas and potentially faster processing.
2Can I use the generated audio for commercial projects?⌄
The licensing terms for commercial use depend on the specific Coqui model and your subscription tier. While some open-source models may permit commercial use with attribution, premium voices or higher volume usage usually require a paid license. Always review the specific model's license or your service agreement.
3How do I access Coqui's advanced voice models or custom voice cloning features?⌄
Access to advanced models, such as those with specific emotional ranges or custom voice cloning capabilities, typically requires a higher-tier subscription or direct engagement with Coqui's enterprise solutions. These features are often managed through a dedicated project dashboard or API access rather than the public web demo.
4Is there an API available for integrating Coqui TTS into my own applications?⌄
Yes, Coqui provides a robust API for programmatic access to its text-to-speech models. API keys can usually be generated and managed from your account dashboard, allowing developers to integrate voice synthesis directly into their applications, services, or content pipelines.
5What audio formats are supported for download, and can I control the sample rate?⌄
The web interface commonly supports WAV and MP3 formats for download. While the default sample rate is often 22.05 kHz or 44.1 kHz, control over specific sample rates or bitrates might be available through advanced settings in a paid tier or via the API for more granular control over audio output.
