- Apple modified audio frequencies during WWDC 2026 keynote to prevent Siri wake-word activation.
- Spectrogram analysis revealed cuts in 3kHz, 4kHz, 5kHz, and 6kHz bands when 'Siri' was mentioned.
- The technique targets acoustic profiles of 'Siri' to reduce inadvertent device triggering.
- Reports indicate the method was not fully effective, with some devices still activating.
- Amazon used a similar frequency-notch technique in Alexa commercials in 2017.
