Known for its accessibility-driven features, Speechify includes the classic WiseGuy voice in its library, allowing students and professionals to listen to documents in this distinctive tone.

Wiseguy voice work involves using AI-driven synthesis to produce audio that mimics a tough, street-smart narrator often associated with urban culture or comedic animation.

Independent developers use wiseguy voices for non-player character (NPC) dialogue to save on localization and studio costs.
