The company says its API will let you synthesize speech in anyone's voice from just a minute-long recording – which means you could, for instance, generate a clip of President Trump declaring war on Canada.
Lyrebird has posted some audio examples that sound pretty convincing (listen below, and find more on this page). The company says that it doesn't require the speaker to say the words that you'll use the voice to speak in the audio you generate, and it'll also be able to create different intonations.
If any of this sounds familiar, it might be because you're thinking of Adobe's demo of its similar tech last November. But while Adobe's Project VoCo requires 20 minutes of audio and appears to use system resources for speech synthesis, Lyrebird only needs a minute-long recording and says it's close to launching its cloud-based API to process audio and spit out results.
