Advanced Training Features​ Built on Years of Audiological Science & Research

Just as physical therapy can help rebuild muscles and adjust movements to compensate for physical weakness or injury, LACE can help you develop skills and learn strategies for dealing with situations when hearing is inadequate.

Speech-in-noise Training

Speech-in-Noise Training

The Speech-in-Noise exercise constitutes approximately 30% of the total adaptive training. This task consists of sentences presented in the presence of multi-talker babble. Training is organized into topics (health issues, money matters, exercise, etc.) that are selected by the trainee at the beginning of the training session in order to reinforce the importance of utilizing contextual cues by keeping the general topic in mind when listening.

Rapid Speech Exercises

The Rapid Speech exercise constitutes approximately 20% of the training. In this task the training paradigm is identical to that of the Speech-in-noise exercise; however, the variable that is modified is the compression ratio (CR) or speed, of the speech signal. The speech signal is based on a typical and average rate of approximately four syllables per second and is initially compressed at a ratio of 0.85 (in other words, the stimuli are compressed to 85% of the normal time).

Competing Speakers

Competing Speakers

The Competing Speaker exercise constitutes approximately 20% of the training. In this task, the trainee is prompted to attend to one of three voices, a male, a female, or a child. The competing speaker is always one of the remaining two voices. In order to reduce frustration, the female’s and child’s voices are never presented together in this task. The precise timing relationship is randomized so that in some instances the target voice has a slight lead, and in others, the background voice may have a slight lead.

Target Word (Auditory Working Memory)

The Target Word exercise is a cognitive training task that incorporates auditory memory. It constitutes approximately 15% of the training. In this task, the trainee is visually presented with a target word. The subject is next prompted to listen to a sentence in quiet. The target word is one of the words in the sentence. Following the auditory presentation of the sentence, the trainee is asked to respond via a multiple-choice option by selecting the word that occurs just prior to the target word in the sentence.

Communication Strategies

Communication Strategies

Periodically, during, and at the conclusion of each exercise, training is briefly interrupted with a differently colored screen. On this screen is a “helpful hint” conveying aural rehabilitation or interactive communication information.
