graphic_eqText to Speech

You direct the read.
The voice follows.

Most text to speech engines read your words. Here you say how they should be read — in a sentence of plain direction, not markup — and the engine performs them that way.

Direction, not markup

Say how it should sound, in a sentence

Other engines read the punctuation and infer a mood — which is why the same sentence comes back cheerful when you needed it grave. Here you brief the read the way you would brief a person, and both engines take the same brief.

Text to speech with emotion — asked for in words

Both engines can sound excited, sad, warm, tense or amused. There is no menu of presets: write the emotion into the direction, as specifically as the scene needs, and the line comes back read that way.

sentiment_very_satisfied

Excited

“Excited, like announcing the winner — quick, rising, a smile in the voice.”

sentiment_dissatisfied

Sad

“Sad and quiet, slow, with a pause before the last word.”

favorite

Warm

“Warm and reassuring, like a nurse explaining the next step.”

bolt

Tense

“Tense and urgent, low voice, clipped sentences.”

From a paragraph to a finished audio file

01

Paste the text

Numbers, dates, currencies and abbreviations are rewritten into speakable words before anything is generated, so "24/7" is not read as a fraction.

02

Choose the engine and the voice

Or add a line of direction instead. The character cost is on screen before you commit, counted against the right pool.

03

Download, or send it onward

MP3, WAV or FLAC by plan. Or keep going — lay it over video in Studio, or hand it to your own systems through the API.

Included on the free plan

A one-off allowance to hear both engines properly before you decide.
