Spec score 8.4 #8 of 25 in AI Singing Voice Generators

What it is

Vocalize generates AI cover songs and text-to-speech using voices from its community library or voices users create. On the web, 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. The searchable library includes uploaded AI voice models and accepts RVC.pth and.index files. Vocalize says text-to-speech takes a few seconds and covers take 10 to 60 seconds; free accounts may wait in a shared queue when demand is high. New signups receive 3 credits without entering a credit card. The REST API supports speech generation, streaming, instant cloning from a 10–30 second clip, direction tags, and 80+ languages. An OpenAI-compatible endpoint can be used for existing /v1/audio/speech integrations by changing the base URL. API usage is prepaid at $0.048 per minute of generated audio plus $0.003 per request, with no subscription. Converter is listed at $9.99 a month, though the page also displays $12.99 and describes paid access as starting at $12.99/mo. Commercial use is restricted unless Vocalize approves it.
