Phonak has just released the myCall-to-Text App for both iPhone and Android. The app enables real-time text transcription of calls. It is free when used between callers who each have the app.
New users get one hour of free use monthly for outbound calls to those not using the app (first three months only), and there are subscription plans for frequent users or to enable transcription of inbound calls from those not using the app.
While the App was introduced in association with launch of Phonak Marvel, it works for everyone (with or without hearing aids; Phonak users or those with other brands). It also is available in multiple languages.
I’ve downloaded but haven’t yet tried it out. Looks interesting, though, and helpful for some folks for sure.
