# ModeValue

The `ModeValue` parameter sets the value of the parameter associated with the speech-to-text algorithm mode specified by the `Mode` parameter.

Setting `ModeValue` high increases the accuracy of the analysis.

- If `Mode=fixed`, the `ModeValue` is the beam width of the search process. A higher beam width than the default leads to slower but possibly more accurate processing, while a lower beam width is faster but probably less accurate.

- If `Mode=relative`, the `ModeValue` corresponds to real-time scaling. The higher the value, the longer processing takes.

- If `Mode=live`, `ModeValue` has no effect.

Type: | Decimal
Default: | 4.0 if `Mode` is set to `fixed` 1.0 if `Mode` is set to `relative`
Ranges: | 1.0–4.0 if `Mode` is set to `fixed` The minimum value if `Mode` is set to relative varies on a case-by-case basis based on the size of the smallest DNN in the language pack, but is typically between 0.5 and 0.9.
Required: | No
Configuration Section: | stt module
