It balances false accepts, false rejects, latency, and power.
Kudzika Kwakadzika
Wake-word detection is a form of keyword spotting. A cascade can use a low-power detector before a more expensive recognizer or assistant pipeline. Hello Edge studies small-footprint keyword spotting under microcontroller constraints. Google research describes contextual speech recognition for trigger phrase detection. A confidence threshold over frames can reduce accidental activations but may increase missed triggers or latency. Hello Edge compares several keyword-spotting architectures on Google Speech Commands under microcontroller resource constraints. Its depthwise separable CNN reports 95.4% accuracy, about 10% higher than a DNN with a similar parameter count in that evaluation. Results are not universal device or language guarantees. A confidence threshold over frames can reduce accidental activations but may increase missed triggers or latency; assess false-accept and false-reject rates in realistic audio.
Kuitwa muNyika yeChokwadi
Run an always-on detector locally and trigger a second-stage recognizer.
Measure false accepts and false rejects on representative audio.
Use acoustic features such as log-mel spectrograms as model input.
Test robustness to noise, accents, and background speech.
Ramangwana reMashoko Akakosha uye Wake Mazwi
Wake-word models continue to improve with distillation and hardware-aware design. Evaluate false-accept and false-reject rates in realistic acoustic conditions and set user controls for microphones and activation.

What is Keyword Spotting and Wake Words?
Keyword spotting detects a specified word or phrase in streaming audio, often to activate a later speech-recognition or assistant stage. It balances false accepts, false rejects, latency, and power.
Ndeipi basa rekutanga rewake-word detector?
A wake-word detector hainyori zvese; inongoratidza chete kana mutsara wakasarudzwa wemutsara wataurwa kuitira kuti system huru igone kumuka.

What trade-off can raising a wake-word detector’s activation threshold create?
A higher threshold can reduce false activations, but may miss quieter or variable pronunciations or require more evidence. Measure false-accept and false-reject rates under realistic conditions.
