Speech perception testing is crucial for monitoring outcomes in individuals with hearing aids or cochlear implants (CIs). Traditional clinical assessments, however, can be time-consuming and challenging given the increasing number of clients. A recent study titled Home-Based Speech Perception Monitoring for Clinical Use With Cochlear Implant Users by van Wieringen et al. (2021) offers a promising alternative: home-based speech testing.
This study investigated three speech perception tasks in 40 CI users: phoneme identification, digits in noise (DiN), and sentence recognition in noise (SiN). The DiN and phoneme identification tasks were performed at home using a tablet, while SiN was administered in the clinic. The findings suggest that DiN scores obtained at home can reliably predict SiN scores obtained in the clinic, making DiN a viable alternative for regular monitoring of auditory performance.
Key Findings and Implications for Practitioners
- High Correlation Between DiN and SiN: The study found a strong correlation between DiN scores and SiN scores (rs = 0.767, p < 0.001). This indicates that DiN assessed at home can serve as a reliable alternative to SiN assessed in the clinic.
- Additional Insights from Phoneme Identification: Phoneme identification in quiet provided significant additional information on the detectability and discriminability of speech cues. This task, which is easy to administer at home, can offer valuable insights into individual performance patterns.
- Measurement Reliability: The study reported that home-based testing with wireless streaming was reliable, with repeated testing yielding consistent results. The average measurement error for DiN was 2.0 dB, indicating high reliability.
- Practical Implementation: Home-based testing can reduce clinical workload, provide immediate feedback, and empower clients to manage their hearing health more effectively. The average usability score for the tablet used in the study was 90.5 out of 100, indicating high user satisfaction.
Practical Steps for Implementation
- Adopt Home-Based Tools: Utilize tablets and wireless streaming devices for administering DiN and phoneme identification tasks at home.
- Train Clients: Provide clear instructions and support to clients on how to use the home-based tools effectively.
- Monitor Regularly: Implement a regular monitoring schedule to track changes in auditory performance and make data-driven decisions for personalized rehabilitation.
- Leverage Data: Use the detailed data from phoneme identification tasks to optimize device mapping and tailor rehabilitation programs.
In conclusion, home-based speech perception monitoring is a reliable and efficient way to complement clinical care for CI users. By embracing these technologies, practitioners can reduce costs, improve access to services, and provide more personalized care.
