[Speech perception. The basis for speech audiometry examinations].
Speech recognition measurements are widely used in clinical applications. Usually, either a speech recognition threshold is determined, being defined as the speech level or signal-to-noise ratio that enables the patient to understand 50% of the target words or target sentences. In other cases, a discrimination curve, describing speech recognition as function of the presentation level, is recorded. For the interpretation of these findings, it is important to keep in mind that speech perception is affected by many interacting sensory, perceptual and cognitive processes.Here, our current knowledge of these processes is outlined and theories that model speech perception in general are briefly reviewed.
