Text to Speech With Emotion, Tone and Accent Control
Paste a script and get a voiceover that sounds performed, not read.
The AI directs the performance
Most text to speech tools leave you two options: pick a voice that only reads one way, or hand annotate your script with markup until it sounds right. SpeechWave works the performance out from the text itself, on two separate layers.
AI Script Enhancer
Works on your script. It reads the text and inserts expression tags where they belong, things like [laugh], [giggle], [sigh], [whisper] and [pause], then cleans up punctuation and pacing so each line lands the way a person would actually say it.
Prefer to direct it yourself? Type the tags straight into your script. The enhancer checks the ones you wrote and makes sure they will work when the speech engine reads them.
AI Voice Direction
Works on the delivery. It generates the performance instruction itself and passes it to the speech engine, something along the lines of "warm, friendly product introduction style, moderate pacing", so the whole read carries one deliberate intention instead of drifting line to line.
That is the difference between a machine reading your words and a performance of them, and it happens without you writing a single direction yourself.
One voice, any mood
A catalogue of 200 voices sounds impressive until you notice the same speaker appears several times over, listed once per fixed performance: one entry reading happy, another reading serious. Choose a different mood and you have switched to a different speaker, and your channel has lost its voice.
24 voices, each fully adaptable
SpeechWave counts base voices, not performances. Every one of the 24 can carry any mood you need, because emotion, tone, accent and pacing are controls you apply to the voice you already chose rather than separate voices you swap between.
So one narrator can front an upbeat ad, a calm tutorial and a serious explainer, and still sound like the same person throughout.
Controls that apply to every voice
Emotion and tone, speaking style, regional accent, and granular speed and pitch, all supported on every voice in the library rather than reserved for particular ones.
Hear it before you write anything: the text to speech demo on our homepage runs the same voices across six different moods.
