Hume Octave
emotion-steerable tts you prompt in words
the model for expressive delivery: octave takes natural-language emotional prompts instead of ssml, so you describe the delivery in words. pricing is reported inconsistently across sources and the ecosystem is smaller.
hume's octave was the first tts to take natural-language emotional prompts rather than ssml — you tell it how a line should be delivered, in words — with expressive, steerable output, voice design and multilingual support. for characters, companions and expressive narration where emotional delivery is the point, it does something the others don't.
the caveats: pricing tiers are reported inconsistently across third parties (confirm on hume's own page), and its ecosystem is smaller than the majors. if emotional control is your feature, it's worth the look.
