Android - How do I disable the google voice typing/voice search 'ding' sound?

Automation is my solution.

There are plenty of automation apps, but I use MacroDroid, since it is easy to learn (that's why I use it) and the behaviour can be easily customized to get the result you want. Besides,free version allows you to create up to 5 macros and so for the task at hand, free version suffices. I prefer automation as a first choice when I need to get something running the way I want rather than depend on an app.

MacroDroid uses macros to perform desired actions.

Macro for your requirement would look like this:

(I am thankful to OP for testing o on his Lollipop based device and confirming behaviour as expected, since my device runs on KitKat and Google has implemented API level changes differently in Lollipop)

Main Macro (working as tested by OP)

Trigger

Application Launched → Google

Action

Volume Change → Configure

Here you get 7 options which can be chosen singly or in combination on a sliding scale from 0 to 100. Options are-
 1. Alarm
 2. Music
 3. Notifications
 4. Ringer
 5. System Sounds
 6. Voice Call
 7. Bluetooth Voice

Choose ((2) Music and (5) System Sounds) and set them to 0 for Lollipop

Choose ((3) Notifications and (5) System Sounds) and set them to 0 for KitKat

( Reason for different selection is explained in Note below)

You can set the (6) Voice call level as desired ( select by testing voice typing comfort level)

Constraints

None

(Macro runs only when constraint is true, so here it runs always)

Save the macro and ensure it is enabled before testing

Optional Macro (Awaiting OP to test)

(In case you need to change volume manually for voice typing, the "ding sound reappears, as reported by OP. This macro is to kill the "ding sound". This macro is not required if you are fine with the voice control level in the main macro and do not need to manually change voice typing volume)

Trigger

Volume Button Pressed → Volume Up → Update Volume

(Followed by)

Volume Button Pressed → Volume Down → Update Volume

Action and Constraints

Same as in the main macro

( Triggers work as logical OR and the action for muting the "ding sound" is triggered whenever the volume is manually increased or decreased for voice typing )

Why this should work for everybody

  1. My search hasn't shown an app or Xposed module that can do this ( not denying the possibility, though)

  2. This macro doesn't require root unlike Xposed approach.

  3. Granular control on different Volume settings. MacroDroid permits you to alter sounds, with a flexibility that is beyond what normally is available in ringer / volume sound control as this example illustrates. My Huawei Honor 6 has only 6 types of volume settings (which is more than some devices offer) but not Bluetooth, which can be controlled through a macro

  4. Customization. You can set "modes", which are like global variables akin to setting profiles. As an example, you can set this macro to run while at home (by mapping cell towers of your home location) and have the "ding" sound active elsewhere. Possibilities for customization are pretty much as you wish

  5. Last but not least, it is free :-)

System Settings

  1. Do not Greenify MacroDroid and exclude it from task killers, if you use them.

  2. Enable MacroDroid in "Auto Protect"(Huawei phones) or "Stamina Mode" (Sony phones or "Power Nap" (Stamina Mode Xposed module for non Sony devices). Also, if you update to Marshmallow in the future, exclude MacroDroid from Doze. Refer this: Is there a way to exclude an app from Doze?

These features prevent app(s) to be active when the device is not awake, conserving battery. May not be pertinent to your phone but adding this as a general precaution.

  1. Enable MacroDroid in accessibility settings and also allow it as device administrator in security settings.

  2. For Lollipop, enable notification access from notification settings

Note

Google Voice Recognition functionality that creates the "ding" sound was streamed as notification stream in KitKat. In Lollipop this is switched to music stream. Hence, in the macro, settings differ.

I have a solution that may be useful ,if not for the OP I hope it will be useful as a reference for shutting the volume of a particular application OFF.

This method will mute all sounds coming from Google App but will not affect the other apps. It works on 4.1 up to Lollipop, but the questioner found that the App Settings Xposed module doesn't work on Marshmallow.

Requirements :

  • Root access
  • Xposed installer Lollipop/Marshmallow / kitkat and older / Stock lollipop Samsung Only (!)
  • App settings xposed Module get it from here (install apk on phone )

Method :

  • make sure app settings is activated in xposed installer under "modules" reboot after activating for the first time.

  • now open App settings and type Google in the search field.

  • You will see in the list the Google App click on it.

  • on the Activity Bar you will see a toggle button toggle it ON.

  • A view with lots of settings will show up ,look at the bottom of the screen just above the permission button there is a check box that say "Mute audio" check it.

  • now click on the save button in the right side of the activity bar and confirm the pop-up message.

  • Now open the voice typing and enjoy the full silence :)

(!) For Samsung devices under Lollipop Follow carefully the thread you must have a deodexed Rom.
