Standalone SDK
Voiceful allows us to create new digital voice experiences for apps and services. It features speech and singing synthesis, transformation, pitch-correction, time-alignment, audio-to-midi, among others.
Our Native SDK can be integrated as cross-platform C++ libraries for Mobile (iOS/Android), Desktop (macOS/Windows/Linux) or Server applications.
TOOLKIT FEATURES
Voice generation | VoSyn
Our expressive voice generation approach, based on Deep Learning, was initially developed to generate artificial singing voice with high realism. It can learn a model from existing recordings of any individual and generate new speech or singing content. +More info
Voice Transformation | VoTrans
We can transform an actor's voice into a monster vocalization for a film, change a male voice into a kid or elder voice, and integrate it in real-time in games, social apps, or music applications. +More info
Voice Alignment and Pitch Correction | VoAlign
VoAlign analyzes and automatically corrects a voice recording without losing quality. We can align it to a reference recording for lip-syncing or ADR, or apply pitch correction automatically to an estimated musical key.
+More info
Voice Description | VoDesc
This voice analysis tool extracts acoustic and musical information from a voice recording. Data can be sent in real-time, or exported in a readable format to be used in applications such as visualization, classification, monitoring or singing rating. +More info
Time-scaling and Pitch-shifting | VoScale
Beyond voice signals, Voiceful includes also a high-quality time-scaling and pitch-shifting to process any audio content (music, field recordings, dialogues, etc). +More info
Mixing and FX | VoMix
VoMix works as a virtual DAW with all standard audio effects (autogain, compression, EQ, reverb, delay, panning, mixing, etc.) to deliver audio in a professional-like quality. +More info
