I have a hard time hearing a conversation in a coffee shop and such places. There are a lot of apps out there that translate speech to text but none that I tried worked unless the people were almost talking right into the cell phone. Any app that will pick up distant speech?
In Michigan There is an organization that provides free texting for HoH and Deaf for landline phones, but they are still working on it for cell phones. You could check with the HoH and Deaf services in your area for recommendations for you needs.You might want to see if Alex will help with changing your title or start a new thread. By saying
need a text-to-speech app for cell phone.
as your title that title is asking for the opposite of what you describe as what you need.
I am trying out Googles new Live Transcribe. It does still make errors but seems better than earlier apps.
