What Lyrebird does
Lyrebird is an AI voice cloning and speech synthesis company founded in 2017 by Alexandre de Brébisson, Kundan Kumar, and Jose Sotelo while researching under Yoshua Bengio at Mila, the Quebec-based AI research institute. Its core technology enables synthesis of a speaker's voice from short audio samples, an approach that has since been embedded into Descript's broader content creation platform following Lyrebird's 2019 acquisition. Today, Lyrebird operates as Descript Research, developing proprietary models including flow-matching transformers, audio editing by latent inpainting, anchored tree sampling, and audio-driven lip-sync, which power consumer-facing features such as Overdub voice cloning, Studio Sound audio enhancement, Regenerate, Remove Filler Words, Eye Contact, and Green Screen.
The company's underlying technology is monetized through Descript's subscription tiers (Free, Creator, Pro, Business) and through an expanding API surface with Model Context Protocol support. Its reach has extended from initial English voice cloning into transcription across 23+ languages, translation across 30+ languages, and broader multimedia tools including AI Avatars, AI Video Generator, Rooms, and Screen Recording. Named customers include SaaStr and LinkedIn, and the platform serves content creators, marketers, sales teams, learning and development functions, customer success teams, and enterprise verticals spanning media, tech, entertainment, customer service, and healthcare.
Lyrebird competes in the broader AI voice cloning market alongside Resemble AI, Descript itself, and iSpeech, but its differentiation stems from academic provenance (Mila/Bengio), continued in-house research, and deep integration with Descript's editing workflow, which together create ecosystem lock-in absent from standalone voice synthesis APIs.
