What part of the paper gives you the impression they imply voice assistants are listening to everything? I don’t get that.

The discussion in the paper is nuanced on that point and does not make that claim as far as I read it. Section 2.2 (page 2):

> The content of users’ speech can reveal sensitive information (e.g., private conversations) and the voice signals can be processed to infer potentially sensitive information about the user (e.g., age, gender, health [82]). Amazon aims to limit some of these privacy issues through its platform design choices [4]. Specifically, to avoid snooping on sensitive conversations, *voice input is only recorded when a user utters the wake word*, e.g., Alexa. Further, only processed transcriptions of voice input (not the audio data) is shared with third party skills, instead of the raw audio [32]. However, despite these design choices, prior research has also shown that smart speakers often misactivate and unintentionally record con- versations [59]. In fact, there have been several real-world instances where smart speakers recorded user conversations, without users ever uttering the wake word [63].

For me, it's this: "Your Echos are Heard"

So, the opening salvo. That's what gives me the impression they imply voice assistances are listening to everything.

I don't refer to voice commands or normal interaction as "echos" so the user of the word "echos" here implies something nefarious. Sure, it's the name of the product, but for me, it reads like something more.

Alexa uses the data we give to it by speaking and performing actions via downloaded skills - is very similar to all ad platforms, conveying user intent into ad profiles.

Saying “process voice for ads” has subtle connotations in the current landscape of privacy discussions.

>Alexa uses the data we give to it by speaking and performing actions via downloaded skills - is very similar to all ad platforms, conveying user intent into ad profiles.

There is an argument that this is more privacy conscience than other ad platforms. One needs to say the word "Alexa" before Amazon will collect any potential targeting data. There is an active and distinct choice that must be made before every interaction. That isn't true for Google and Facebook. They will collect data in the background while you are doing other things. There is much less transparency in when and how they are collecting their targeting data and therefore we have much less agency in the process.

As clarification, you are objecting to the phrase “process voice to [serve] ads” in the title which was provided by the submitter not the paper authors?
From the abstract:

> We find that Amazon processes voice data to infer user interests and uses it to serve targeted ads on-platform

For example, this sibling comment: https://news.ycombinator.com/item?id=31178067
Unlike other ad platforms, Amazon claims that they do not use voice data for ad targeting. From paper:

Amazon has publicly stated that it does not use voice data for targeted advertisements [83], [75].

I'm sure Amazon isn't processing voice data to target ads. Why would they need to?

They're using skill interaction, order history, listening history, etc to target ads.

"Subtle connotations" are not much to make an objective complaint out of.
