# ModeValue

The meaning of this parameter depends on the value of the Mode parameter:

- If the `Mode` parameter is set to `fixed`, `ModeValue` specifies the beam width to use. The beam width affects how IDOL Speech Server searches for recognized word sequences. You can set a value between 1.0 and 4.0. A higher beam width can produce a more accurate transcription but processing might be slower.
- If the `Mode` parameter is set to `relative`, `ModeValue` specifies a factor that represents the data processing rate compared to real time. You can set a value between 0.25 and 4.0. A value of `0.25` processes data four times as fast as real time, while `4.0` processes data four times slower than real time. The higher the value, the longer processing takes.
