AI girlfriend voice chat or a real call: how to tell them apart
Read the pricing page before the marketing page. Text to speech is cheap to run, so it sits on the free or entry plan. Live voice costs the company money every minute, so it lands behind the top tier or a per minute charge. When a plan advertises voice with no minute count anywhere on the page, it is almost always text to speech.
What voice actually costs
Three billing models cover nearly all of it. Some apps bundle a monthly allowance of minutes, which is the easiest to reason about. Some spend your token or credit balance, so voice competes with image generation for the same pot. A few charge per call on top of the subscription, and those are the ones where a long evening gets expensive without any warning on screen.
Latency and memory, the two things nobody advertises
Under a second feels like talking to someone. Two or three seconds feels like a bad line, and you start speaking over each other. Memory is the other one: an app can sound wonderful and still forget the previous call entirely, which turns every conversation into a first date.
Does an AI girlfriend call work like a phone call?
You are talking to an app over your data connection, not over the phone network. Nothing here dials your number. That means you need signal, your provider is not involved, and nothing shows up on your phone bill.
