A comparison of cochlear implant processing strategies in children using speech pattern audiometry

Area of Science:

• Audiology
• Speech-Language Pathology
• Biomedical Engineering

Background:

• Cochlear implants (CIs) are vital for hearing restoration in children.
• Speech processing strategies significantly impact CI users' auditory perception.
• Evaluating these strategies requires effective audiological tools.

Purpose of the Study:

• To compare phoneme perception between SPEAK and ACE processing strategies in pediatric CI users.
• To assess the utility of Speech Pattern Audiometry (SPA) for evaluating CI speech processing.

Main Methods:

• Utilized Speech Pattern Audiometry (SPA) with pediatric Nucleus 24 cochlear implant users.
• Assessed phoneme perception using two synthetic word pairs: voicing and place of articulation contrasts.
• Compared performance between the SPEAK and ACE speech processing strategies.

Main Results:

• The ACE strategy showed more normalized phoneme boundaries than the SPEAK strategy for both word pairs.
• A trend, though not statistically significant, indicated better identification abilities with ACE compared to SPEAK.
• SPA proved effective in differentiating performance between the two strategies.

Conclusions:

• ACE processing strategy may offer advantages over SPEAK for phoneme perception in pediatric CI users.
• Speech Pattern Audiometry (SPA) shows potential as a clinical tool for evaluating CI speech processing strategies in children.
• Further research is warranted to confirm the benefits of ACE and the role of SPA in clinical practice.
