I need to use some hands free apps through a bluetooth handset (e.g. cyberon voice commander, Klets, and others).
All these hands free apps use the voice recording function of the phone to acquire the voice.
I noticed very bad accuracy in voice recognition using the BT headset. I tried to record voice through the headset and discovered that the recording is very bad, low volume and noisy. While if I record directly through the phone mic it is crystal clear.
I tried with different BT headsets and the result is the same.
Nevertheless voice conversation over the BT headset is working well.
Any one as experienced the same behaviour and/or found a solution?
XPeria Z2 with Stock ANdroid 4.4.4 rooted
Any news on this issue? Will it be addressed in the 5.0 upgrade from Sony?
Bug: Voice cancellation while BT recording
I have investigated on this issue and learned that Sony firmware after Andriod 4.4.x activate voice cancellation while Bluetooth recording.
This reduces the voice recording quality and accuracy rate of voice recognition.
Sony, when you will solve this bug?

I am having an issue with sound quality out of Acer Iconia A501 tab with Honeycomb 3.2 installed (ROM Harkon 1.0, KERNEL HoneyVillian 3.7). Unfortunately I didn't test it with the stock ROM.
The problem: voice sound in video/voice chat software (Skype, CSipSimple etc.) is of very poor quality (very low volume and very high amount of background noise, as if i'm talking from a closet). The same is true for various voice recording apps.
The only exception so far is TapeMachine.
If I use a _wired_ mobile phone headset AND record using TapeMachine with AutoGain turned off and Input gain set to +20dB, the voice recording is of very good quality, clear and loud. But with the same headset the sound through Skype Echo Test Service is awful. A strange and a very disappointing thing is that with a built-in mic the same TapeMachine settings do not produce any change in voice quality - it was still awful.
Sound Meter reports my background sound (with the headset) at 40dB when silent and 65-70dB when talking.
My understanding of the issue is that starting with API Level 11 (Honeycomb 3.0) voice/video chat software uses android.media.MediaRecorder.AudioSource.VOICE_COMMUNICATION audio source, which is a "Microphone audio source tuned for voice communications such as VoIP. It will for instance take advantage of echo cancellation or automatic gain control if available. It otherwise behaves like DEFAULT if no voice processing is applied."
And it seems like it's not working very well.
My question is: could somebody, please, develop a hack that would allow tweaking of system wide echo cancellation and automatic gain control settings if that's at all possible?
Or is there any other solution?
Thank you!
Is there a way to increase the clarity and volume of voice during calls?
Pantech Burst with stock firmware ICS. Will installing CM10 fix it?
Using a MP3 voice recording app, it isn't bad. But during calls, the voice that's transferred over is terrible quality, static-y, and half the volume of a normal phone recording.
I have the same problem but I'm on stock 4.0.4. Microphone works fine if I use the voice recorder. However, on phone calls, my voice isn't picked up well (tested by recording outgoing message on my voice mail). I notice that if I cover the rear mic (don't know if that helps) and speak directly into the mic (which requires that I remove my ear from the speaker), my voice is picked up much better. However, this form of talking (where I can only hear or talk but not both at the same time) isn't practical in a conversation.
I have a non-rooted Asus Zenfone 5 with recent OTA firmware. When I attempt a normal voice call or Skype call the microphone is muted i.e. I can hear the caller but they can't hear me.
Other microphone related activies such as Sound Recorder, Google voice search and Keep voice note work fine. Using a microphone headset doesn't make any difference.
I've searched through every setting imaginable and tried a few mute apps from Google Play and no luck.
Any feedback is appreciated.
when calling if i use with speaker for hands-free use my voice listen with cuts like bad signal,i have 2 phones with the same problem.
Voice recording with distortions.
video recording work fine.
I have made an observation in Android Marshmallow (I know, not the newest, but I still want to find answers to this mystery):
Audio recording (using com.nll.asr) blocks video recording.
Audio recording during phone call is possible.
My question is:
How come (technically) that the telephone application is able to access the microphone simultaneously with the voice recorder, while the camera can not?
What is the technical reason for that?

Trivial observation: In Android 4.4.2, the audio recorder and torch app keeps the LED on and the ASR voice recorder keeps recording during shutdown.
