Currently, Octave supports English and Spanish, with more languages planned for future releases. English has the most comprehensive support with the fullest range of voice capabilities.
Effective voice descriptions include details about demographics (age, gender, background), speaking style (pace, energy, formality), personality traits, professional roles, or emotional states. For example: "A middle-aged university professor with a gentle but authoritative voice, speaking deliberately with occasional moments of dry humor."
Yes! When you generate a voice you want to use again, you can save it to your personal voice library. The number of voices you can save depends on your subscription plan, with higher tiers allowing for more saved voices.
Voice Description defines the base characteristics of the voice (who is speaking), while Acting Instructions guide how that voice performs a specific piece of text (how they are speaking). For example, you might have a "professional male news anchor" voice (description) that you want to speak "excitedly" for one segment and "solemnly" for another (acting instructions).
