Custom Hotword with Snowbow

francesco

Hi, first of all thank you for the fantastic modules you have done.
I wanted to ask you if it is possible to use a modified hotword for the ext-detector module… in particular I would like to use the linked guide to create my own .pmdl model in order to activate GA with the hotword “francesco” instead of the universal models like Jarvis, Hey Goole, etc…

try this in detectors:

        detectors: [
          {
            detector: "Snowboy",
            usePMDL: true,
            PMDLPath: "./../../../",
            Model: "francesco",
            Sensitivity: null
          }
        ]

Copy your francesco.pmdl file into EXT-Detector root direcftory

Model : Filename of your pmdl (without extension)
usePMDL: true,; is (the secret) flag for enable PMDL mode
PMDLPath: "./../../../",: path since the library … don’t modify … just copy this

Hi! I have tried and it works.
However i need to adjust the sensitivity because the detector activates too often…
Do you have some advice?

bugsounet

adjust your mic level and Sensitivity field

Note: You can use EXT-Volume for volume control

francesco

OK thanks! Are there any recommended settings or I try randomly?

bugsounet

I can not advise adjustment, it depends on your microphone

sample:

Actually: I use C270 webcam mic, mic level is 25%
Previouly: with other USB mic: level is 40%

(with Sensitivity: null)

best way:
using Gateway app and adjust mic level in live

Aftyer when you find the best value, report it EXT-Volume in config

Ok thanks for the tips!
I have the same microphone (logitech webcam c270). Do you think it’s a good mic or should i change it for something else like ps3 eye or this?

I have use this usb mic next time, I works fine (I have use it ~ 2 years)
now i use C270 mic since i code EXT-Selfies suite and EXT-Motion detector (and turn off my EXT-Pir)
