Hello,

As per the subject matter, I read about how to use Google Assistant on an android mobile/tablet instead of a separate smart speaker (Google Home/Mini). The functionality would be more or less similar with some exceptions with both the options. (comparisons are available around on different sites). Dont want to use the internal device mic/speaker, so looking for options for hooking up external mic/speakers.


  1. [1]I was thinking of a setup to have an external wired mic hooked up to the tablet as being more sensitive to capture a wide area. I know I have to use a TRS to TRRS adapter to be able to hook up only a mic to the headphone jack on any standard android device. I believe android would still detect it as a headset (with microphone and speakers). I have an Audio-Technica ATR-4697 boundary mic which I intend to use for the purpose.

    [2]For the audio output I am thinking of hooking up a Bluetooth speaker (always connected on charging) making it sort of a DIY smart speaker.

Can someone please inform if they have done a similar setup and how successful was it , and what are the main problems and not working functions.

One problem I can foresee is that due to point no.1 , the android will try to route the audio via the headphone jack, which would only have a mic connected.

I believe this can be forcefully redirected using the SoundAbout app, will it work.

Or else I can try to get a Y Splitter cable hooked to the headphone jack and connect both a wired mic and a wired AUX in speaker for the purpose. Not sure whether the Y splitter cable would have the same TRRS 3.5mm comaptible pin to hook up to the mobile head jack.

Any thoughts, guidance, product links would be appreciated.

Thanks.
