I want to get a wav format voice through my microphone.  
(For use with IBM STT)  
For the "node-red-contrib-mic" package, voice input is not working.

For the microphone node in the "node-red-contrib-browser-utils" package, voice input works. However, it is difficult to use it on IoT devices because the input is performed by clicking the button directly.

Is there only a way to click on a node in the browser screen to perform input from node-red?

For example, I want to use something like a GPIO button as a trigger of this flow.

Step 1 would be to search on [flows.nodered.org](http://flows.nodered.org) for any other nodes that might do what you are looking for. For example theres a node for USB microphones.

Certainly, lots of ways. Here are a few off the top of my head:

- Use an Amazon Alexa or Google Home interface
- Raspberry Pi running Node-RED, wire up a button to a GPIO
- Use Dashboard for a web interface
- Use a hacked Amazon button
- Create an ESP8266 or ESP32 based button interface over WiFi :
- Create a Telegram bot for a command or conversational interface 🤖
- Use the IFTTT "Do" app
- Wire up a soil sensor so that you trigger the flow when you water a plant 🥀
- Use a light sensor for hands-free activation 🕶
- ....

Why not use several? There are examples around for all of these.
