Android Question Recorded Voice Message by phone

[kokoroayo]

Hi all,

I am working on a project for a client. It monitors appointment of patients to a doctor and sends SMS to patients to remind them of their appointment. This is so far working well.

Now I have a challenge. A new addition has been introduced which means I have to deliver a pre recorded audio message to the patient by phone call.

Use of MMS is not an option as not all of them have Multimedia capable phones. So we thought we should:
1. Have the message Recorded and stored as an audio file on the phone
2. Let the app make a phone call to the recipient
3. Once phone call is picked, the recorded message is played instead of human voice conversation.

Please point me in the right direction on this

Thank you in advance.

You can capture audio with AudioStreamer.

However it is not possible to directly inject the captured audio to the phone call. You can play it in the background and the microphone will capture it. You need to test whether the quality is good enough.

Thanks Erel. I'll think around that.
However, ive been looking at the project on streaming over bluetooth. Just wondering if same can be achieved over a call.

No. It is not possible. See my previous answer.
