Emvoice vs Revocalize AI

Emvoice One is a paid vocal synthesis plugin for programming notes and lyrics that a voice engine renders as sung audio. Its editor uses a piano-roll timeline with pronunciation and phoneme controls, and follows the host DAW's tempo and time signature. The cloud engine rebuilds vocals from recorded phoneme samples, sending generated audio back over the internet, so an internet connection is required for editing and rendering. Emvoice One runs on macOS and Windows in VST2, VST3, AU, and AAX formats. Listed hosts include Logic Pro, Ableton Live, Studio One, REAPER, Bitwig, and Cubase. Demo versions of every available voice are included; purchasing a voice unlocks its full version, with 10 presets per voice at no extra charge. MIDI support is listed, and commercial use is allowed. A continuous region can contain up to 20 notes. One plugin instance cannot run two lyric-and-melody sets for self-harmonization. Project files use VP1 and user dictionaries use UD1.

Revocalize AI creates AI voices and trains custom voice models using voice-synthesizing technology. Its voice-conversion service captures a voice's harmonics and transforms an input voice into another. Listed tools include voice beautification and transformation, emotion, language versatility, real-time auto-pitch, vocal variations, and pitch, volume, and speed controls. Music creators can use the VST plugin for voice transformation, beautification, and harmonizing; compatible hosts named on the site include Logic Pro, Ableton, and FL Studio. Beta API documentation describes voice-to-voice conversion, text-to-singing, and speech, with access beginning by creating an account and API key. The site names sound engineers and producers, labels and publishers, artists and creators, and music enthusiasts and fans as use cases. Its Free plan includes 5 conversion minutes per month and one Starter AI voice. Starter costs $9 a month for 120 minutes and two Ultimate AI voices; Creator costs $39 a month for 300 minutes and five Ultimate AI voices. The VST plugin is listed for a 49.00 USD one-time payment. Exports include MP3 and WAV. Users are responsible for their uploaded or created content and may not create content that infringes others' rights.
