When your smart speaker knows too much and the court wants to hear it

With the modern home now more interconnected than ever, smart speakers such as Amazon's Alexa have become as commonplace as a refrigerator or television. They play music on command, tell you the weather, and sometimes even laugh at your jokes (or in more creepy scenarios, laugh without any reason). But with great connectivity comes great responsibility: what happens when Alexa knows something crucial about a legal case? Could your trusty home assistant one day be called to the witness stand?

"I'm sorry, I can't assist with that..."

Imagine this: A dispute arises over whether you gave a verbal agreement to a neighbor to trim a tree that's causing damage. Your neighbor insists you did, but you're certain you didn't. The only 'witness' to the conversation is Alexa, which was streaming your favorite tunes at the time. Could Alexa's recording of the ambient sound and conversations be subpoenaed?


In recent years, several cases have made headlines where law enforcement sought data from smart speakers to aid in investigations. The data mined from these devices can include voice recordings, transcriptions, and other pertinent user data. The rationale? If Alexa is always listening (primarily to hear its wake word), it might just have caught some vital information.

The Great Privacy Debate

The tech industry's giants, including Amazon, have often stressed that their devices prioritize user privacy. Alexa, for example, only starts recording after hearing its wake word and quickly forgets what it doesn’t save. But "quickly" in machine terms might still be enough for the device to catch and process crucial snippets of your discussions.

With the potential of these speakers to serve as electronic eavesdroppers, they naturally become gold mines of information. And like any treasure, there's a rush to claim it. While companies like Amazon have resisted some subpoenas to protect user privacy, there's no blanket immunity. In cases where a serious crime might be prevented or solved, the scales might tip towards disclosure.

Legal Implications and Considerations

If your Alexa device becomes a potential witness, several legal questions arise:

  1. Relevance & Reliability: Is the data on the device directly relevant to the case? And if so, how reliable is it?

  2. Consent: Given that the primary user has accepted terms of service, do they (or should they) have a say on how this data is used in a legal scenario?

  3. Chain of Custody: Ensuring the device's data hasn't been tampered with can be a challenge, especially if it's been accessed multiple times or by multiple parties.

  4. Data Interpretation: With voice recognition still being an imperfect technology, how certain can we be of the context and content of the recordings?

Wrapping Up: A Future of Digital Witnesses?

While it might be a while before we see an Alexa device seated in the witness box with a lawyer grilling it with questions, the implications are clear. As our devices become smarter and more integrated into our daily lives, the lines between convenience and surveillance, privacy and disclosure become blurrier.

For now, it might be wise to consider what you say around these smart devices. After all, Alexa might just be the silent observer holding the key to the truth. And in the courtroom of the future, her recollections might just be the evidence that tips the scales of justice.

*One of my favorite things about ChatGPT-4 is its power to inspire creativity. For example: I wanted to generate an article about an interesting topic. First, I prompted GPT-4 to generate a list of titles for articles about law and tech. Next, I picked some of the most interesting titles and asked GPT-4 to write articles using those titles. After refining with a few prompts, the article you just read was one of the results. I especially liked this article because it generated legal questions. Any one of these questions could be a good jumping off point to a research paper. Sometimes getting started is the hardest part, and GPT-4 solves that problem.

A lot of people I've talked to are focused on the dangers of GPT-4 and other AI advances. But what sort of problems could be solved by generative AI and other new technology?
