17.6 Using Speechmap

The Speechmap fitting environment provides a number of distinctly different stimuli. Speech and noise are analyzed in 1/3 octave bands and (except for pink noise) data are presented as 3 curves. The top curve is the level exceeded 1% of the time (speech peaks), the lower curve is the level exceeded 70% of the time (speech valleys) and the middle curve is the average. Starting a test causes the signal to be presented continuously - the speech signals run in a loop - and the curves are updated frequently to show any changes you make to the hearing instrument. Pressing <Continue> restarts the speech passage and the curves are then calculated for the entire passage, producing an accurate display of the speech region and LTASS, and an accurate SII calculation. When using live speech, a <Freeze curve> button captures short-term speech features. See 17.10: SII calculation in Speechmap and 19: Speechmap Technical Details.
