What Determines Speech Understanding?

Please note: exam questions are subject to change.

1. We typically perceive the speech signal at the sub-phoneme level at the phoneme level at the syllable & word level at the paragraph level
2. The form of a spoken phoneme Is always the same Will be affected by other nearby sounds Is always produced the same way by a given talker None of the above
3. The acoustic approach to explaining speech understanding Helps to focus on the most important frequency regions Helps to predict how much audibility is sufficient Helps guide the setting of gain and frequency response All of the above
4. The "Triple X" concept refers to: Fine tuning in low, mid and high frequencies Synthesizing speech cues across frequency, time and ears That a single phoneme can be produced in different ways That all listening situations have at least three sources of competition
5. When we say "the speech signal is redundant", we are referring to the use of contextual cues linguistic cues multiple acoustic cues within phonemes all of the above
6. Stream Segregation allows the listener To determine if the talker is actually getting around to the point of what he is saying To listen in just one frequency region Disentangle one talker from another over time Hear only one class of phonemes at a time
7. Speech competition Is typically harder to suppress Is typically easier to suppress Is captured realistically using recordings of babble Is equally as disruptive as speech noise
8. The Pickett Fence studies tell us Listeners cannot listen in the gaps of interference Competing speech is actually easier to suppress when complete Interrupted speech is more mellow to listen to All of the above
9. Speeding up the incoming speech signal Has no effects on the acoustics of the phonemes Will improve stream segregation May be particularly disruptive for older patient showing age-related cognitive declines Will separate it from the background
10. The combination of sensorineural hearing loss and normal age-related cognitive declines Can occur either separately or together Indicate the proper aided AI score Have opposite, cancelling effects on speech understanding Minimize the listening difficulties of patients with hearing loss only
