Audio AI
Cover Song Identification
Cover song identification detects when two very different-sounding recordings are actually the same underlying song — a live acoustic version, a remix…
Audio AIDDSP Differentiable Audio Synthesis
DDSP (Differentiable Digital Signal Processing) fuses classic synthesizer building blocks with neural networks, so deep learning can control oscillators…
Audio AIVITS End-to-End Speech Synthesis
VITS is a text-to-speech model that turns text directly into raw audio waveforms in a single trained system, skipping the usual two-stage pipeline.
Audio AIFastSpeech and Non-Autoregressive TTS
FastSpeech generates an entire speech spectrogram in parallel rather than one frame at a time, making synthesis dramatically faster and more stable.
Audio AINaturalSpeech and Latent Diffusion TTS
NaturalSpeech is a line of Microsoft TTS research aiming for human-level speech quality, with later versions using latent diffusion to generate rich, natural…
Audio AISpeech Emotion Recognition
Speech Emotion Recognition (SER) is AI that detects a speaker's emotional state — anger, joy, sadness, frustration — from the sound of their voice, not just…
Audio AIMoshi Full-Duplex Speech
Moshi is an open-source, real-time voice AI from Kyutai that talks and listens at the same time — full-duplex — instead of taking strict turns.
Audio AISpeech-to-Speech Translation
Speech-to-Speech Translation (S2ST) takes spoken words in one language and produces spoken words in another — ideally preserving the speaker's voice, tone…
Audio AIHiFi-GAN and GAN Vocoders
HiFi-GAN is a generative-adversarial vocoder that turns a mel-spectrogram into a raw audio waveform almost instantly, producing studio-quality speech far…
Audio AIGrapheme-to-Phoneme Conversion
Grapheme-to-phoneme (G2P) conversion translates written letters into the sounds a speech system should actually pronounce.
Audio AIText Normalization for Speech
Text normalization is the front-end step that rewrites raw written text into fully spoken-out words before a speech system says it.
Audio AISoundStream Neural Codec
SoundStream is Google's end-to-end neural audio codec that compresses speech and music to extremely low bitrates while preserving quality.
