Python Extract Speech From Video

Posted on by halilintar8

Alhamdulillaahi rabbil ‘aalamiin sudah berhasil long video chunk nya,
ternyata secara tidak sengaja saya sudah mengutak-atik program machine learning (ml) 🙂 ,

termasuk salah satu impian saya ini program translate/subtitle speech/video to text,

i’m not a developer software, because i don’t build it (from start),
and i’m not a programmer too, because i’m not making any program (from start),
maybe i’m just a modifier 🙂 ,

next to do lists :
– make the program to be more precise in subtitle/transliterate/translate
– make the converted file (wav) to become more tiny size (ex: mp3)
– make the .srt or embed (hardcode) it to the video, but i think this is a video editing work 🙂 .

Ternyata github code saya yang ini, sudah dilihat oleh teman (web dev) kantor lama saya, qa engineer yang sekarang, dan it manager suatu perusahaan startup 🙂 .

Ubuntu 22.04 Lenovo laptop internal microphone not working in Gmeet Google Chrome browser

Posted on by halilintar8

This workaround has been tested and worked in Ubuntu 22.04, and should be working too for Ubuntu 20.04, 18.04, and a few earlier.

No microphone input on Acer Aspire One and Lenovo Ideapad 310-15ISK/330-15ARR

Install pavucontrol, unlink the microphone channels and turn down the left one to 0.

  • apt install pavucontrol
    run pavucontrol (pulse audio volume control) from terminal or applications

Some applications (e.g. chromium) can change microphone levels causing the same issue, a workaround is to remap stereo input to mono and use the remapped device as default.

Another Possible Cause

Another possible cause is that your mic has two channels but only one channel can provide a valid sound signal. Some information can be found here. The solution is to remap the stereo input to a mono input:

1. Find your source name from the following command; mine is alsa_input.pci-0000_00_1f.3.analog-stereo

pacmd list-sources | grep 'name:.*input'

2. Edit /etc/pulse/default.pa and add the following lines, where INPUT_NAME is name of the input source from above step:

load-module module-remap-source source_name=record_mono master=INPUT_NAME master_channel_map=front-left channel_map=mono
set-default-source record_mono

3. Restart PulseAudio:

$ pulseaudio -k
$ pulseaudio --start

Now arecord hopefully works. You may still need to change the RecordStream from setting to Remapped Built-in Audio Analog Stereo of a specific application in the Recording tab of pavucontrol.
