Vocalize
Sheridan, Wyoming, United States
What it is
Vocalize is a web and API service for generating AI cover songs and text-to-speech from community-uploaded voices or voices users create. Users can train a text-to-speech voice from a short audio sample or make a voice-to-voice RVC model for singing and voice swapping. A searchable library offers user-uploaded AI voice models and accepts RVC .pth and .index files. The service says text-to-speech takes a few seconds and AI covers take 10 to 60 seconds; free accounts may wait in a shared queue during busy periods. New signups receive 3 credits without a credit card. Its REST API supports speech generation, streaming, instant cloning from a 10–30 second clip, direction tags, and 80+ languages, plus an OpenAI-compatible endpoint for existing /v1/audio/speech integrations. API use is prepaid, with no subscription, at 0.048 USD per minute of generated audio plus 0.003 USD per request. Converter is listed at $9.99 a month, while the page also displays $12.99 and paid access is described as starting at $12.99/mo. Commercial use requires Vocalize’s approval.
