Resemble AI is a Toronto and San Francisco company founded in 2019 by Zohaib Ahmed and Saqib Muhammad to make synthetic voices for game studios. For five years it sold voice cloning, text-to-speech and speech-to-speech through a web studio and API, raising an $8 million round in July 2023 and later a $13 million round aimed at AI-generated threats. In August 2026 Ahmed published a post titled "Why a former voice AI company went all in on deepfake detection" confirming the company had stopped selling voice generation to new customers. Existing voice customers are still supported. Resemble also retired more than 300 older blog posts on voice cloning, which is why many old links now land on that announcement. Anyone researching Resemble as a voice generator should treat it as a detection vendor with a voice research arm.
The current product is a set of five APIs. Detect returns a verdict on whether audio, video or an image is synthetic in under 300 milliseconds, according to the company. Watermarker embeds an inaudible or invisible mark at the point of generation and reads it back after compression and re-encoding, with C2PA support. Identity enrolls a known voice and face, then checks whether an incoming call or video matches it. Signal matches calls against libraries of known fraud patterns without storing transcripts, and Intelligence turns a detection score into plain-language reasoning and JSON. Ready-made products sit on top: meeting protection for Microsoft Teams, a Chrome extension that flags deepfakes in the browser, and agent detection for spotting AI callers. A typical deployment pipes contact-center audio or uploaded media through Detect and routes flagged items to an analyst.
The main limitation for most readers is that Resemble no longer sells the product it was known for. Teams that want hosted voice cloning should look at ElevenLabs, which offers instant and professional cloning from $5 a month, or Respeecher for studio-grade speech-to-speech. Developers comfortable running models themselves can use Chatterbox from Resemble's own repository at no cost, but without a commercial voice service behind it. On detection, Resemble competes with Reality Defender and Pindrop, which also sell real-time deepfake screening to banks and call centers; Resemble's edge is that it publishes self-serve prices and an API key you can get without a sales call. Pick Resemble if you need to screen calls, meetings or uploads for synthetic media. Look elsewhere if you need to generate voices.
