I have a Story Builder application for parents to design customized stories for their children. The user can choose a "Read to Me" feature which uses TTS by HUME AI. One thing that happens to be very entertaining to children when reading a story to them is to incorporate onomatopoeia or some other types of vocal bursts. So the inclusion of this feature does drive engagement and retains audible interest.

User @kirkrock in Discord reports this would be extremely useful for their TTS application that reads children's stories.

Being able to laugh when the user makes a joke is, in my opinion, an essential for immersive "empathic" voices. As Francisco referenced, Dia has this capability and its certainly imperfect at times but it'd be great if this was considered for Hume.

Yeah, what Dia (https://fal.ai/models/fal-ai/dia-tts) does with its non verbal sounds is awesome!

Generate non-verbal like (laughs), (coughs), (clears throat), (sighs), (gasps), (singing), (sings), (mumbles), (beep), (groans), (sniffs), (claps), (screams), (inhales), (exhales), (applause), (burps), (humming), (sneezes), (chuckle), (whistles)
