Properties

customLexiconUrl	URL of a custom lexicon file for pronunciation customization.
customTextNormalizationUrl	URL of a custom text normalization endpoint.
locale	Enforced locale in BCP-47 format for TTS output. If set, TTS will always use the specified locale to speak. For example, setting locale to en-US forces American English accent for all text content, even if the text is in another language, and TTS will output silence for unsupported languages (e.g., Chinese text with en-US locale). If not set, TTS automatically detects the language from the text content.
name	Voice name cannot be empty.
pitch	Pitch adjustment for the voice output. Follows the same rules as the pitch attribute of the SSML prosody element (see https://learn.microsoft.com/azure/ai-services/speech-service/speech-synthesis-markup-voice#adjust-prosody). Typical values: a named level (x-low, low, medium, high, x-high, default), a relative change (e.g., +10%, -5%, +50Hz, -2st), or an absolute frequency (e.g., 200Hz).
preferLocales	Preferred locales in BCP-47 format that change the accents of languages. If not set, TTS uses the default accent for each language (e.g., American English for English, Mexican Spanish for Spanish). Setting this to ["en-GB", "es-ES"] changes the English accent to British English and the Spanish accent to European Spanish, while TTS can still speak other languages like French or Chinese with their default accents.
rate	Speaking rate adjustment for the voice output. Follows the same rules as the rate attribute of the SSML prosody element (see https://learn.microsoft.com/azure/ai-services/speech-service/speech-synthesis-markup-voice#adjust-prosody). Typical values: a named level (x-slow, slow, medium, fast, x-fast, default), a relative percentage (e.g., +20%, -10%), or a non-negative multiplier (e.g., 0.5, 1.5).
style	Speaking style for the voice (e.g., 'cheerful', 'sad').
temperature	Temperature must be between 0.0 and 1.0.
type	The discriminator possible values: azure-custom, azure-standard, azure-personal, avatar-voice-sync
volume	Volume adjustment for the voice output. Follows the same rules as the volume attribute of the SSML prosody element (see https://learn.microsoft.com/azure/ai-services/speech-service/speech-synthesis-markup-voice#adjust-prosody). Typical values: a named level (silent, x-soft, soft, medium, loud, x-loud, default), an absolute number from 0.0 to 100.0, or a relative change (e.g., +10, -6dB).
