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. Contact us for an evaluation account.
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
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
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
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
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
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
See below an example code for integrating our SDK tools in C++.
