SoulX-Singer vs VoiSona Song

SoulX-Singer is a singing voice synthesis model that generates voices for singers it has not been tuned on. Pitch, rhythm, and expression can be guided by melody-conditioned F0 contours or score-conditioned MIDI notes. Its voice-conversion system changes raw singing audio to a target singer’s voice while retaining melody, rhythm, and lyrics, without requiring lyric or MIDI transcriptions. It supports Mandarin Chinese, English, and Cantonese, plus singer-timbre cloning, cross-lingual synthesis, and lyric editing while retaining natural prosody. Preprocessing tools handle vocal separation, dereverberation, F0 extraction, voice activity detection, and lyric and note transcription. Users can edit MIDI metadata, including lyrics, phoneme alignment, pitches, and durations, before synthesis. Soul-AILab provides generation and conversion demos and a separate MIDI editor through Hugging Face Spaces; the repository also supports local inference. Code and model weights use the Apache 2.0 license. Maintainers caution that automatic preprocessing may misalign singing with lyrics and notes, so manual correction may be needed.

Editing controls cover phoneme timing, pitch, volume, vibrato, voice quality, and huskiness. On PC, the app can run on its own or as a VSTi or Audio Units plug-in. The iOS/iPadOS app runs standalone or as an AUv3 plug-in compatible with GarageBand, Logic Pro, Cubasis, and more.

Sign-up is required, and an internet connection is needed for installation and some features. CeVIO Creative Studio and CeVIO AI exclusive voice libraries cannot currently be used.
