We found and created the persona for Samsung Bixby in cooperation with Samsung.  We did within a period of 1.5 years all TTS recordings in New York City with the one chosen talent. We coordinated, recorded and supervised it. If you are looking for a partner helping you with Text-To-Speech recordings (TTS) we are the people to ask.
