Do I have to touch the screen at all?
No. Once cook mode is open and listening, the wake word plus a command moves through the whole recipe. You need your hands for the first tap and nothing after that.
Why is the wake word so strict?
Because a recipe step that begins "Next, add the onions" would otherwise skip itself. Only real transcriptions of "SpiceGuy" count, which is what makes it safe to leave listening while you cook.
Does it work if the kitchen is noisy?
It uses your browser's own speech recognition, so it needs a working microphone and a reasonably quiet moment to hear the wake word. Extraction fans and running taps will beat it — the on-screen controls are always there as well.
Is cook mode free?
Step-by-step cook mode is free on every plan. Voice control, the screen wake lock and concurrent named timers are part of SpiceGuy Pro.
