Talkapella iPhone App Magically Transforms Speech Into 4-Part Harmony

Khush, the Company Behind Songify and LaDiDa, Is Profitable With More Than 80M Songs Created (October 13, 2011)

ATLANTA, GA -- (Marketwire) -- 10/13/11 -- Khush, the music creation company behind iPhone app sensations LaDiDa and Songify, today introduces Talkapella, an iPhone app that magically transforms speech into 4-part harmony. Khush uses advanced artificial intelligence technology to make music creation easy using the iPhone. Khush is profitable, and more than 80M songs have been created using its apps. Talkapella is free in the iTunes App Store, and can be downloaded at

"LaDiDa and Songify have been downloaded more than 7 million times, and Khush is profitable on a minimal amount of funding -- this is clear evidence that there's a market for apps that help people express themselves with music," said Prerna Gupta, founder and CEO, Khush. "Our goal is to make music self-expression as ubiquitous as social expression. User demand for an a cappella version of Songify has been enormous, and we're thrilled to bring Talkapella to market."

Talkapella is based on a sophisticated speech-to-music technology that builds on the concept of AutoTune. A user's speech is intelligently mapped to four voices to create a rich vocal harmony. Just like a real composer, the artificial intelligence maps the speech patterns to the musical patterns, so the words match the phrase of the melody. This is done by intelligently stretching and compressing the speech based on the location of vowels and consonants. The result is a magical transformation of speech into a killer a cappella track.

Khush is a spin-off from Georgia Tech, based on a "reverse karaoke" technology developed by co-founder Parag Chordia. Chordia and co-founders Gupta and Alex Rae commercialized the technology and formed Khush. Parag remains a professor at Georgia Tech, and is the head of the university's Music Intelligence Lab.
