Works well and easy to use.
It's been while since I bought this and had a quick play with it, but now it's been integrated into an actual project I'm happy to review it as being very good - I've found it recognises phrases easily. It maybe could do with having more customisable phrases as a lot of the pre-programmed ones are quite specific and won't be used, but for the price it's pretty good.

Very good, needs occasional reboot
Works surprisingly well. I'm using it with an ESP32. I was particularly impressed with the fact that I can record a command with my male voice and the device will recognize that same command from my wife's voice. I do wish it had an external microphone connector instead of an external speaker connector. Like others have said, it does seem to stop responding to the wake command about an hour after booting up. It's easy enough to just have the ESP32 reboot it periodically but it would be better to just not. All in all, if you're making a robot and considering this, buy it, you won't regert it.

Gute "Nuschelbox" für kleines Geld, mit Potential
Schönes Ding ich nenne es die "Nuschelbox" schade das man nicht alle Befehle ändern kann, aber dafür kann man ja ein paar eigene Befehle mit eigener Sprache festlegen und wenn man dann auch ungefähr die Betonung wieder trifft klappt es auch ganz gut mit der Sprachsteuerung. Auch die erkennungsreichweite finde ich beeindruckend (man muss nicht direkt davor kleben). Für ein IVR System würde ich sagen unbrauchbar aber als alternative zu gängigen Sprachgesteuerten Online Smarthome lösungen definitiv eine gute wahl dadurch das kein Internet benötigt wird.

Fonctionne très bien
On peut créer un mot de réveil en français. et 17 commande en français personnaliser. Ces mots peuvent être des sons. Je le met en mode muet car il respond qu'en Anglais. une del bleu me dit qu'il attend une commande.

Works as promised and easy to add to existing or new projects.
Very easy to set up. I am using this board with an Arduino Mega 2560. BTW I had better luck using the IC2 protocol and connecting to the SDA and SCL imputs on the Ardunio vs using UART communication. Coming up with lots of ideas on how I can use this! Search for "SKU SEN0539-EN Gravity Voice Recognition Module I2C UART" to locate the operator manual on how to train and use this board with sketches. You only have 17 custom commands you can add to the existing fixed commands (over 100) which are listed in the manual but that is plenty for what I am doing.
