Magnetic implants with sensors for electronic Larynx

An electro larynx, sometimes referred to as a "throat back", is a medical device about the size of a small electric razor used to produce clearer speech by those people who have lost their voicebox, usually due to cancer of the larynx.

Its digital speech recognition systems measure the spoken sound and identify the output through various methods. As one of the methods, the most common of which include magnetic implants with sensors which focus on measuring the key articulators (i.e., velum, tip and body of tongue, and lips).
