apply_text_normalizationenum or nullOptional

This parameter controls text normalization with four modes: ‘auto’, ‘on’, ‘apply_english’ and ‘off’. When set to ‘auto’, the system will automatically decide whether to apply text normalization (e.g., spelling out numbers). With ‘on’, text normalization will always be applied, while with ‘off’, it will be skipped. ‘apply_english’ is the same as ‘on’ but will assume that text is in English.
