The Gandr exchange, the history of voice on the wire

The wire’s century

1878, now

One wire. Every voice on it.

A century of the same line, and what was speaking on it each time.

Automatic switching retires the cords, nobody speaks on the wire for a generation.

Formant synthesis puts a robotic voice on the phone, everyone learns to shout “representative”.

Neural TTS makes the machine voice warm again, and the new exchanges bill the conversation by the letter.

The exchange

The voice business is older than the telephone bill.

Five eras of the wire, one live switchboard, and the reason our invoice has no meter.

Recovery calls that keep the customer.

We know, because we were on that meter.

us

We were the customer before we were the company.

We ran a product that spoke to thousands of people at once, and every vendor sold us the same thing: a cap we outgrew, and a meter that punished us for growing.

the answer

We built the voice we couldn’t buy.

So we built Spex-TTS, on capacity we hold open ourselves, fast enough to answer inside a breath and priced like infrastructure rather than ink.

the mission

Everything is learning to speak. Gandr exists to be its voice. Everywhere, unmetered, measured in milliseconds.
