Hi,

I want to develop an Amazon Alexa interface on the Gear S3.
First I need to record voice and then send it to my companion app running on the Android side.
How can I record the voice ?
after recording it, shall I be able to send it through SAP ?


thanks.

Please go through VoiceRecorder sample app from Tizen Studio. It contains code snippet corresponding to voice recording and saving it as an amr file. You may send that file to your Android app using SAP. Please go through FileTransfer sample app from SAP SDK samples. Hope it'll help you.

voicerecorder is a very complex sample.
It is written in a manner that includes several js file and makes undertsanding very difficult.

I checked to see what it does after recording is stopped.

it fires the event "recording.done" in the main.js
then the show() function is called in the preview.js 

but I still could not find where the file is recorded.

it says:
audio.src = detail.audio;


so, does this have the path to the recorded file ?
if yes, I can send it to the android phone using SAP file transfer.

I guess the Web Recorder sample isn't storing the voice into fileSystem, May be it's just storing the buffer on local variable as the size is kept fixed and little.

Most Probably the Web API used in this Tizen Web application is general Web audio recording procedure, may be using getUserMedia() API. If you developing a web application then search in the internet for voice recording Web API. It doesn't need to be Tizen API explicitly; any Web API to record audio would do if Tizen web supports  it.


And If you are interested in Tizen Native application then, There's Tizen Media Recording API:
