What You'll Learn
When to Use Advanced Techniques
Try basic techniques first! Before diving into advanced respelling, make sure you've tried the essential optimization methods covered in Optimizing AI Videos and Audio.
Use these advanced techniques when:
Basic hyphens don't fix the pronunciation - "con-tent" still sounds wrong
Acronyms need precise control - You need "NASA" to sound exactly like "nassa"
Emphasis isn't working - Quotation marks aren't giving you the inflection you need
Complex technical terms - Medical, scientific, or industry-specific words
Multiple pronunciation attempts failed - You've tried everything else
These techniques work for both:
AI-generated video cards
AI-generated audio cards

The Respelling System: Complete Control
The respelling system gives you precise control over exactly how the AI pronounces each syllable and which syllables receive emphasis.
How Respelling Works
Respellings tell the AI the exact sound each syllable should make using a phonetic format.
Format: ::phonetic-spelling::
All respellings are:
Contained within double colons
:: ::Written in lowercase letters
EXCEPT for emphasized syllables (which are UPPERCASE)
Basic Example
Word: Studio
βRespelling: ::STOO-dee-oh::
βResult: Emphasis on "STOO," followed by "dee" and "oh"
Word: Content (the noun, not the adjective)
βRespelling: ::KAHN-tent::
βResult: First syllable emphasized, sounds like "con" not "kun"
When to Use Respelling
β Use respelling when:
Hyphens aren't precise enough
You need exact syllable emphasis
Technical terms require specific pronunciation
You've tried multiple simpler methods without success
β Don't use respelling for:
Simple words where hyphens work fine
Words the AI already pronounces correctly
Every word in your script (use strategically)
Problem: Acronyms Sound Wrong
Common issues:
Acronym is pronounced as a word when you want individual letters
Acronym is spelled out when you want it said as a word
Emphasis is on the wrong letter
Solution: Acronyms as Words
For an acronym that should be pronounced like a word, spell it phonetically or use respelling.
Problem: FEMA sounds awkward
βSimple fix: feema
βAdvanced fix: ::FEE-muh::
Problem: NASA doesn't sound natural
βSimple fix: nassa
βAdvanced fix: ::NA-suh::
Problem: ASAP sounds wrong
βRespelling: ::AY-sap:: or ::eigh-SAP::
Solution: Initialisms (Individual Letters)
For acronyms that should be pronounced letter-by-letter, use spaces or respelling.
Problem: FBI sounds like "fibby"
βSimple fix: F B I
βAdvanced fix: ::ehf-bee-Y::
Problem: NYC doesn't sound right
βSimple fix: N Y C
βAdvanced fix: ::ehn-wy-SEE::
Problem: MOM should be letters, not "mom"
βSimple fix: M O M or M-O-M
βAdvanced fix: ::ehm-OH-ehm::
Respelling Guide for Acronyms
When respelling initialisms where each letter is spoken individually, use:
ABCDEFGHIJKLMNOPQRSTUVWXYZ β
β::ay-bee-see-dee-ee-ehf-jee-aych-y-jay-kay-ehl-ehm-ehn-oh-pee-kyoo-ar-ehs-tee-yoo-vee-DUH-buhl-yoo-ehks-wy-ZEE::
Examples:
LCD β
::ehl-see-DEE::BBC β
::bee-bee-SEE::HR β
::aych-AR::
Problem: Words Are Mispronounced
Common issues:
Shorter words sound unnatural
Longer technical terms are butchered
Foreign words or names sound wrong
Solution: Shorter Words
For shorter words, spell them phonetically.
Problem: "edamame" sounds wrong
βSolution: edamawmay
Problem: "aΓ§ai" doesn't sound right
βSolution: ah-sigh-ee or ::ah-SY-ee::
Problem: "quinoa" is mispronounced
βSolution: keen-wah or ::KEEN-wah::
Solution: Longer Words
For longer words, break them into syllables and adjust only the problematic syllable.
Problem: "triiodothyronine" (medical term)
βSolution: "try idoe thighro neen" (include quotation marks)
Problem: "antidisestablishmentarianism"
βSolution: Break it: anti-dis-establish-ment-tarian-ism or use partial respelling
Tip: Use quotation marks around complex phonetic spellings to help the AI recognize them as pronunciation guides.
Solution: Using the Respelling System
For precise control, use the respelling format with the phonetic charts below.
Problem: "desert" (dry place) sounds like "dessert" (sweet food)
βRespelling: ::DEH-zert::
Problem: "present" (gift) sounds like "present" (to show)
βRespelling: ::PREH-zent:: (gift) vs ::prih-ZENT:: (to show)
Problem: Emphasis Is Wrong
Common issues:
Wrong syllable is emphasized
Key words don't stand out
Tone doesn't match intent
Solution: Using Quotation Marks
Place quotation marks around words or phrases that need emphasis.
Problem: Need to emphasize a specific word
βSolution: This is the "most important" step
Problem: Multiple words need emphasis
βSolution: "Complete this task" before moving forward
Solution: Emphasizing Specific Syllables
Use respelling to control which syllable gets emphasis (UPPERCASE = emphasized).
Problem: "PROduce" (vegetables) sounds like "proDUCE" (to create)
βSolution: ::PROH-doos:: for vegetables
βAlternative: "pro"duce (quotation marks around first syllable)
Problem: "REcord" (noun) sounds like "reCORD" (verb)
βSolution: ::REH-kord:: for noun, ::rih-KORD:: for verb
Problem: "CONtent" (what's inside) sounds like "conTENT" (satisfied)
βSolution: ::KAHN-tent:: for noun, ::kuhn-TENT:: for adjective
Problem: Questions Don't Sound Like Questions
Common issues:
Upward inflection is missing at the end
Questions sound like statements
Tone feels flat
Solution: Inflection Techniques
Try these methods to get natural question inflection:
Method 1: Record multiple takes
Generate 2-3 versions without changesβyou'll notice subtle differences in AI performance.
Method 2: Add comma before final word
βHow are you doing, today?
Method 3: Remove end punctuation
βHow are you doing today (no question mark)
Method 4: Combine punctuation and quotes
βHow are you doing, "today"?
βHow are "you" doing, "today"?
Method 5: Emphasize words mid-sentence
βHow are "you" doing today?
Try different combinations until you get the inflection you need.
Problem: Numbers Sound Wrong
Common issues:
Reference numbers sound like values
Years sound unnatural
Phone numbers aren't pronounced correctly
Dollar amounts are confusing
Solution: Reference Numbers and Pages
Use spaces between digits to get individual number pronunciation.
Problem: "1246" sounds like "twelve forty-six"
βSolution: 1 2 4 6 (sounds like "one two four six")
Problem: Room number "305" sounds like "three hundred five"
βSolution: 3 0 5 (sounds like "three oh five")
Solution: Dollar Amounts
Format dollar amounts to match how you want them pronounced.
Problem: "$1,200,000" sounds awkward
βSolution: $1.2 million (sounds like "one point two million dollars")
Problem: "$500" needs to sound casual
βSolution: 500 bucks or five hundred dollars
Problem: Want just the number, not "dollars"
βSolution: 1.2 million (without $ sign)
Solution: Years
Format years based on desired pronunciation.
Problem: "2022" should be "two thousand and twenty-two"
βSolution: 2,022
Problem: "1999" should be "nineteen ninety-nine"
βSolution: Leave as 1999 (AI naturally pronounces this way)
Problem: "2000" needs specific pronunciation
βSolution: two thousand (spell it out)
Solution: Phone Numbers
Use spaces between digit groups for natural pronunciation.
Problem: "(206) 555-3131" sounds robotic
βSolution: 2 0 6 5 5 5 31 31
Problem: Want "triple five" instead of "five five five"
βSolution: 2 0 6 triple 5 31 31 or spell it: two oh six, triple five, thirty-one thirty-one
Problem: Pacing and Rhythm Feel Off
Common issues:
Script sounds rushed
Not enough breathing room between ideas
Sentences run together
Need longer pauses in specific places
Solution: Strategic Punctuation
Different punctuation creates different pause lengths and tones.
Commas (,)
Add small, subtle pauses
Use where a voice actor would breathe
Example:
First, complete the form. Second, submit it for review.
Periods (.)
Create longer pauses with downward inflection
Best for breaking long sentences into pieces
Example:
This is important. Let me explain why.
Ellipses (...)
Create "breathing room" between sentences
Add slight dramatic pause
Example:
Remember...It's essential to create an environment that encourages success.
Combination punctuation (.,.,.,.)
Creates custom pause lengths
Experiment with different combinations
Example:
Let's pause here.,.,.,.before continuing.
Solution: SSML Break Tags
For precise pause control, use break tags (covered in basic guide, but worth repeating):
<break time="2s" /> - Creates a 2-second pause
β<break time="500ms" /> - Creates a half-second pause
Use break tags when:
Punctuation doesn't give you the exact pause you need
You want consistent pause length
You need very short or very long pauses
Phonetic Reference Charts
Use these charts with the respelling system (::phonetic::). The column headers work like fill-in-the-blank:
"To hear 'a' as in all, type AW. Example: ::AWL::"

How to Use These Charts
Find the sound you need in the "as in" column
Use the corresponding phonetic code from the "type" column
Build your respelling between double colons:
::CODE::Capitalize syllables you want emphasized
Example: To make "water" sound natural:
w = W
a (as in "all") = AW
t = T
er = UR
Result:
::WAW-tur::or::WAH-tur::
Common Problems and Solutions
"I've tried everything and it still sounds wrong"
Try these last-resort techniques:
Try a different voice (audio cards) or avatar (video cards) - some handle specific sounds better
Rewrite the sentence - sometimes changing the context helps
Break into multiple cards - complex pronunciation might work better in shorter segments
Use simpler language - if a technical term won't work, find an alternative
Contact support - we can help troubleshoot stubborn cases
"The respelling makes it worse"
Common respelling mistakes:
Wrong capitalization: Remember UPPERCASE = emphasis
Missing colons: Must be
::text::not:text:ortextIncorrect phonetic codes: Double-check against the charts above
Too many syllables respelled: Try respelling only the problematic part
"I don't know which phonetic code to use"
Strategy:
Say the word out loud slowly
Break it into syllables - wa-ter, com-pu-ter
Match each sound to the "as in" column
Use the corresponding code from the charts
Test and adjust - you may need to try 2-3 variations
"Should I respell every word?"
No! Only respell words that:
Are mispronounced after trying basic techniques
Need precise emphasis control
Are technical terms the AI doesn't recognize
Most words should be left normal - overuse of respelling makes scripts hard to maintain.
Best Practices for Advanced Techniques
Start simple, go advanced only when needed:
Try basic hyphens first
Then try punctuation changes
Then try quotation marks for emphasis
Finally, use respelling if nothing else works
Keep your scripts maintainable:
Document why you used respelling (add a comment for yourself)
Don't respell words unnecessarily
Test after each change
Save versions that work
Test with different voices/avatars:
Audio cards: Try different voice options
Video cards: Try different avatars
Some may handle your specific content better
When respelling doesn't work:
Try breaking the word differently
Use quotation marks around the phonetic spelling
Consider rewriting the sentence

Common Questions
Q: Should I use these techniques for every video or audio card?
A: No! These are advanced techniques for stubborn pronunciation issues. Most content works fine with basic optimization or no changes at all.
Q: Can I combine respelling with SSML break tags?
A: Yes! You can use ::respelling:: and <break time="1s" /> in the same script.
Q: Do these techniques work in all languages?
A: The respelling system and phonetic charts are designed for English. Other languages may require language-specific phonetic approaches. Basic techniques (hyphens, breaks, punctuation) work across all languages.
Q: Why are there different phonetic codes for the same letter?
A: Because letters make different sounds in different contexts. "A" sounds different in "ant," "all," and "ate" - each needs its own phonetic code.
Q: How do I know if I'm using the right phonetic code?
A: Generate the video/audio and listen. If it's not right, try a different code from the charts. Pronunciation fine-tuning often requires iteration.
Q: Can I use partial respelling (only some syllables)?
A: For best results, respell the entire word. Mixing normal text with respelling codes can confuse the AI.
Q: What's the difference between "text" and ::text::?
A: Quotation marks add emphasis to normal text. Respelling (::text::) uses phonetic codes to control exact pronunciation. They serve different purposes.
Q: These charts are overwhelming. Do I need to memorize them?
A: No! Keep this article bookmarked as a reference. Most users only need to look up a few codes for specific problem words.
Q: Can I create my own phonetic codes?
A: Try the codes from the charts. The AI is trained to recognize these specific phonetic symbols.
