Voices Obscured in Complex Environmental Settings (VOiCES)

automatic speech recognition denoising machine learning speaker identification speech processing


VOiCES is a speech corpus recorded in acoustically challenging settings, using distant microphone recording. Speech was recorded in real rooms with various acoustic features (reverb, echo, HVAC systems, outside noise, etc.). Adversarial noise, either television, music, or babble, was concurrently played with clean speech. Data was recorded using multiple microphones strategically placed throughout the room. The corpus includes audio recordings, orthographic transcriptions, and speaker labels.

Update Frequency

Data from two additional rooms will be added to the corpus Fall 2018.
