Doubao Speech Synthesis Large Model 1.0
What This Is
The first-generation large model speech synthesis from Volcano Engine's Doubao Speech, with the official product name "Large Model Speech Synthesis". Compared to the small model (BV voices), the voices are more natural and have stronger emotional expressiveness. It is currently the default tier for Doubao Speech in Soniva.
Suitable Scenarios
Daily voiceovers, assistant broadcasts, audiobook narration — for users who prioritize sound quality and naturalness in general scenarios and are not particularly price-sensitive.
Voices
The voice list is pulled in real time from the Volcano Engine API, typically containing over 300 voices. The specific number is subject to what you see in the product (it will change as Volcano Engine adds new voices on its own, without requiring a new release from Soniva).
It covers categories such as general scenarios, role-playing, fun dialects (Bay Area Uncle, Adorkable Sichuan Girl, Beijing Lad, Guangxi Yuanzhou), education scenarios (Teacher Tina, supporting Chinese-English bilingual), and multilingual. Dialect voices are only available in 1.0; 2.0 currently has no corresponding version.
