With this parameter enabled, the pronounced words will be compared to the reference text. The language code wasn't provided, the language isn't supported, or the audio file is invalid (for example). If you select 48kHz output format, the high-fidelity voice model with 48kHz will be invoked accordingly. Fluency indicates how closely the speech matches a native speaker's use of silent breaks between words. These scores assess the pronunciation quality of speech input, with indicators like accuracy, fluency, and completeness. The input. Custom Speech projects contain models, training and testing datasets, and deployment endpoints. Projects are applicable for Custom Speech. A resource key or authorization token is missing.
