Chris has personally written over 2,000 articles that have been read more than one billion times-and that's just here at How-To Geek. For example, Google told Wired that 'around 0.2 percent of all recordings' are ever listened to.Ĭhris Hoffman is the former Editor-in-Chief of How-To Geek. Microsoft contractors are listening to Cortana voice commands and even parts of some Skype calls, according to a Motherboard report on August 7, 2019.ĭespite the lurid details, most recordings are never listened to.Contractors say they frequently 'hear drug deals, medical details, and people having sex,' according to a report by The Guardian on July 26, 2019. Apple contractors regularly listened to Siri recordings.Google contractors have listened to some clips from Google Assistant, according to Belgian public broadcaster VRT in a report published on July 10, 2019.

The report says thousands of workers around the world are listening. Amazon workers are listening to Alexa audio clips, according to a Bloomberg report from April 10, 2019.Nearly any company offering some sort of voice-powered service has someone listening-at some point. And, considering voice assistants might accidentally activate in the middle of a conversation, it means that people could end up hearing snatches of potentially personal information. But many people are surprised to hear it. This is all allowed in the fine print you already agreed to when signing up for any of these services. Many companies peek at the data you store with them and use the information they find for various purposes. Developers can then use this information to improve the assistant and its capabilities. But companies may have a contractor listen to a few seconds of recordings later and see how the assistant did.įor example, if the assistant didn't understand your question or provided a wrong answer, the contractor can note what happened. Most conversations are never listened to. These are anonymized, which means the contractors can't see your name or any personal information. Tech companies have employees-or, more often, contractors-listen to snippets of the conversations you have with voice assistants and other services. One big problem that I'm encountering is that the thresholder catches the quiet portions of speech as turnoffs (generally followed almost immediately by another turnon).Why Are Companies Listening to These Recordings? I am having some difficulty in figuring out what the proper settings for the thresholder should be, and I'm also wondering if there are any other pd components that might be useful. I am trying to use a combination of an envelope follower () and a thresholder () to create the start and stop events. Looking at the audio I've recorded directly from the headset, it's pretty obvious to human eyes when a participant is speaking, and when they are not, as the SNR is fairly high.

Essentially logging the times that participants start and stop talking.Įach player has a bluetooth headset with a noise-cancelling microphone. As the next step in this research, I need to be able to detect when each player is speaking to the others - voice activity detection.

I've been using pd to mix audio, provide sound effects, and record audio for my dissertation project - a serious game for teaching team members to coordinate.
