Why isn’t speech recognition used in hearing aids?

Question by al mond: Why isn’t speech recognition used in hearing aids?
Hearing aids represent a billion dollar industry, yet the quality of understandability using these aids is fairly poor. It is not unusual for a hard of hearing person to spend thousands of dollars for hearing aids only to relagate them to the dresser drawer.

Best answer:

Answer by MistWing
1. The software needs to learn how a person speaks. When you have a random person speaking, the software hasn’t learned to understand that person.

2. The size of the components. You would need a fast processor, significant memory and a larger power source to make it work.

3. Speech recognition software may inappropriately try to translate non-speech sounds, or sounds from a crowd. This would make the sound even more unintelligible

    WAY too complicated!

    What with all the variable differences in diction, intonation, projection, dialect, impediments and accent.

    The brain is what recognizes speech and language, so using speech recognition software wouldn’t help at all.
    In recent years, with the development of digital hearing aids, sound quality has gotte MUCH better, with only sounds in the speech frequencies being amplified. Most background (“ambient”) noise is not amplified.
    Hearing loss by nature results in distortion of the sounds heard by the patient; it’s not the hearing aid’s fault. Because digital aids can be programmed to fit the contour of the hearing loss, distortion is reduced but cannot be eliminated entirely.
    The best thing a hearing-impaired individual can do is to see an audiologist, who can then recommend the aid most appropriate for the type and configuration of that loss. I would avoid a hearing aid dealer (Sonus, HearX, or Beltone) simply because they typically don’t have audiologists on staff and are interested in selling hearing aids. An audiologist is much more interested in finding the right aid for the job.
