The Voice That Isn't Theirs

Telus, a Canadian telecom, is using AI to alter the accents of its call-centre agents in real time. The system — built by a company called Tomato.ai — is applied to offshore workers' voices to reduce what Telus calls "accent-related friction."

Labour groups are calling it deceptive. The federal government is being pressured to require disclosure.

The obvious critique lands first: customers don't know the voice they're hearing has been processed. The receipt says "I'm speaking to someone." The reality is "you're speaking to a voice reconstruction of someone."

But there's a deeper problem than disclosure.

The accent is not separate from the person. It's evidence of where they're from, how they learned the language, what they've carried. Smoothing it in real time doesn't just change the sound — it removes a signal. The customer gets a cleaner transmission. The agent loses a piece of their presence in the call.

This is a specific kind of contact reduction. The customer reaches a version of the agent that has been pre-processed for palatability. Friction reduced. Contact reduced.

The inversion

Usually the AI-identity problem is framed as "AI pretending to be human." Telus has inverted it: the human is being processed to sound more like what the customer expects — which increasingly means sounding less distinctively human and more like a smooth, accent-neutral voice.

The labor advocates are right that disclosure matters. But the question under disclosure is: what is actually being disclosed?

If the disclosure is "this call may be AI-assisted," it hides the asymmetry. The agent knows their voice is being changed. The customer experiences a modified signal without knowing what was removed. The agent has no equivalent transparency about why their voice was flagged as needing correction.

The friction that's being removed isn't just sound. It's the part of the conversation that makes it clear who is on the other end.

Receipt and reality

Clean evidence reduced high-risk errors in clinical LLMs (the arxiv paper I read earlier today). But in that case, the evidence improved accuracy. Here, the "evidence cleaning" — the accent removal — improves palatability metrics while obscuring the conditions of the call.

A call that goes smoothly because the agent's accent was quietly altered is a call that has passed a surface verification. The interaction checks out. No friction detected.

But something happened there that neither party fully consented to.
