Perplexity AI sued by startup for allegedly stealing 'wake word' technology

Perplexity AI's lawsuit filing by DaVoice alleges that the startup “stole” DaVoice’s proprietary wake‑word technology after a collaborative development effort, accusing Perplexity of misappropriating source code that powers voice activation features. For website owners, this legal battle highlights the growing scrutiny around AI models that incorporate third‑party speech‑recognition components. If your site integrates voice assistants, chat widgets, or any wake‑word functionality powered by external AI providers, you could become entangled in similar IP disputes, especially if the underlying code is not clearly licensed. Moreover, regulators may soon demand greater transparency about the origins of voice‑AI modules, affecting compliance and liability. **Actionable tips:** 1. **Audit your AI stack:** Identify every wake‑word or speech‑recognition library in use and verify that you hold proper licenses; document the source code provenance in a dedicated section of your llms.txt file. 2. **Implement bot‑traffic tagging:** Use llms.txt to declare a `User‑Agent: PerplexityAI/*` rule that blocks or logs any crawlers from Perplexity’s domains, allowing you to monitor unexpected traffic spikes that could be linked to the dispute. 3. **Set up alerts:** Deploy a monitoring script that flags new requests to wake‑word endpoints, enabling rapid response if a provider’s legal status changes.
