Read on to fully understand what this job requires in terms of skills and experience If you are a good match, make an application. Voice AI today cannot holdreal conversations. It requires walkie-talkie style turns, lacks empathy and has an inconsistent personality. Developers are unable to build long-form experiences out of the box. And users disengage because the interaction feels unnatural.
