Stop guessing which emotions to add.
Levizr's AI Emotion Enhancer reads your entire TTS script, understands the intent behind each sentence, and automatically places the right emotion tags in the right places. One click. Full undo. 20 credits flat.
How the AI Emotion Enhancer works
The Enhancer is not a simple find-and-replace or keyword detector. It uses a language model to read your script the way a voice director would — understanding mood, sentence intent, pacing context, and audience expectation before making any tag placement decision.
Paste your script
Type or paste your full TTS script into the Levizr Studio editor. The Enhancer works on any text — short ad copy, long audiobook chapters, podcast intros, or social media voiceovers.
Click the Enhance button
Hit the Enhance Emotions button (pencil icon, top-right of the editor). Levizr sends your text to the AI which analyzes sentence intent, mood, and pacing context to determine the optimal emotion placement.
Review the enhanced script
Your script reloads with emotion tags inserted as visual chips. You can see exactly what was added, where, and why. Every chip is editable — click to remove any tag you disagree with.
Undo with one click if needed
Not happy with the result? The Enhance button turns into an Undo button the moment enhancement completes. Click it to restore your original script exactly as it was. No credit wasted on a re-generation.

When should you use the Enhancer?
The AI Emotion Enhancer is not always necessary — if you already know exactly which emotions you want, manual tagging gives you more control. But here are the scenarios where the Enhancer saves significant time and improves output quality.
You're unsure which emotions to add
If you're new to emotion tags or working with an unfamiliar content type, the Enhancer takes all the guesswork out. It reads your script like a director would and inserts tags where they make the most contextual sense.
Your script is long and tagging manually would take too long
Manually placing 20-30 emotion tags across a 500-word script is tedious. The Enhancer does it in seconds, analyzing the full context of each sentence rather than just picking random emotions.
You want a first draft to refine
Use the Enhancer as a starting point. Let it auto-tag the script, then go through and swap out any tags that don't feel right. It's much faster than starting from scratch.
You need consistency across a series
For podcast episodes or audiobook chapters, the Enhancer applies a consistent emotional logic across each piece — so your series sounds tonally coherent even when written over different sessions.
Flat 20-credit cost per enhancement
The AI Emotion Enhancer costs a flat 20 credits per use regardless of whether your script is 50 words or 1,000 words. The analysis runs on the full script context. After enhancement, if you generate speech, the standard per-character credit rate applies to the script text only — the tags themselves are not charged.
Frequently Asked Questions
What is the AI Emotion Enhancer in Levizr?
The AI Emotion Enhancer is a one-click feature inside Levizr Studio that automatically reads your TTS script and inserts contextually appropriate emotion tags in the right places. It uses an AI model to understand the sentiment and intent of each sentence before placing any tag.
How many credits does the AI Emotion Enhancer cost?
The AI Emotion Enhancer costs a flat 20 credits per use, regardless of script length. This is separate from the credits used for the actual speech generation. The cost is for the AI analysis, not the output length.
Can I undo the enhancement?
Yes. The moment the Enhancer finishes processing, the pencil icon changes to an X (undo) button. Clicking it restores your original script exactly as it was before enhancement, with no loss of text or formatting.
What intensity level does the Enhancer use?
The Enhancer applies tags at a moderate intensity — meaning it targets the highest-impact moments and leaves neutral passages untagged. This approach produces more natural-sounding results than tagging every single phrase.
Does the Enhancer work with multilingual scripts?
The Enhancer can process scripts in multiple languages, but its contextual accuracy is highest for English content. For Hindi, Hinglish, or other languages, the enhancement may still produce reasonable results — but we recommend reviewing and adjusting the tags manually after enhancement.
Is the AI Emotion Enhancer available on the free plan?
The Enhancer is available to all registered Levizr users. You need a Levizr account (free to create) and sufficient credits. The base credit allocation on sign-up covers several Enhancer uses.
