The AI Voice Tool: Text-to-Speech That Sounds Human on WorkCrafter

The voice tool turns a script into natural-sounding speech for narration, videos, ads, explainers and accessibility. This guide covers the engines, how to write a script that reads well aloud, and how to avoid the robotic delivery that gives text-to-speech a bad name.

The voice engines

Pick an engine per generation depending on what you need from the voice:

• Automatic (recommended): a natural, general-purpose voice. Start here.
• Standard voices: clean, neutral delivery for straightforward narration.
• Expressive: more emotion and dynamics — good for storytelling, ads and anything that should feel alive.
• Multilingual: for scripts in, or mixing, multiple languages.
• Voice clone: reproduce a specific voice from a sample (only with the speaker's consent).
• Designed voice: craft a voice to a description when you want a specific character rather than a stock read.

“The engine sets the timbre; your script sets the delivery. Punctuation is how you direct the pauses and the pace.”— WorkCrafter

Write for the ear, not the eye

Text that reads fine on a page can sound stilted aloud. A few habits fix most of it:

• Use short sentences. The voice breathes at full stops — long sentences run out of air.
• Punctuate for rhythm: commas for short pauses, full stops and line breaks for longer ones.
• Spell things phonetically when a name or acronym is mispronounced ("see-kwel" for SQL).
• Write numbers the way you'd say them ("twenty twenty-six", not "2026") when the reading matters.
• Read your script out loud first — if you stumble, the engine will too.

Getting a natural delivery

If a read sounds flat, the fix is usually the script, not the engine. Break dense paragraphs into shorter lines, add commas where a person would pause, and switch to the Expressive engine for anything with emotion. For long pieces, generate in sections — it's easier to redo one paragraph than a ten-minute take.

A note on voice cloning

Voice clone is powerful and easy to misuse. Only clone a voice you own or have explicit permission to use. Impersonating someone without consent is both against the rules and, in many places, illegal.

What it costs

A voice generation costs 10 credits (1 credit = $0.01). Failed generations are refunded automatically, so it's cheap to try a line on two engines and keep the better read.

Frequently asked questions

Why does my narration sound rushed?

Not enough punctuation. The voice pauses at commas and stops — add them where a person would breathe, and split long sentences in two.

Which engine for a YouTube voiceover?

Expressive usually wins for video: the extra dynamics hold attention. Standard is better for calm, informational reads where neutrality is the point.

Can I use the audio commercially?

Yes for the generated speech under the platform's terms. The exception is cloned voices — you need the rights to the underlying voice as well.

Start narrating

Open the voice tool, paste a short, well-punctuated script, and try it on Standard and Expressive to hear the difference. Generate long pieces section by section for full control.
