# Glossary

Telereader uses a small, deliberate vocabulary. The words here
are the ones the product uses in the UI; they are also the words
the docs use, the marketing site uses, and the support
conversations use. Picking one word per concept and sticking to
it is what keeps the product calm.

## Voice

The sound that reads the words. Each voice has a tone — warm,
crisp, measured — that you pick by ear. "Voice" is also what
you change when you want a different sound; it is not a setting
called something else.

## Listening

What you do while the voice reads. You are listening; the reader
is reading. Avoid words like *playback session*.

## Reading

A single piece of text and the audio that goes with it. A blog
post is a reading. A book chapter is a reading. A pasted email
is a reading. The library lists your readings.

## Library

The page that lists your readings. Tap any reading to open it.
The library is yours; it does not have categories or tags
imposed by the product.

## Credit

The unit of paid work. You see credits in the billing area when
you have an account and have added them. Pricing terms — what
counts as a credit, how many credits a reading uses — are on
the plans-and-pricing page.

## In-browser

Generation that happens inside the tab you are reading in. No
network round-trip for the audio itself; the words are read by
your device.

## On our servers

Generation that happens on Telereader's servers. The audio is
delivered to your device as it becomes ready. Choosing this mode
is opt-in and shown before the work begins.
