Getting AI to Pronounce Names and Unusual Words

Quick answer: When an AI singer mispronounces a word, respell it the way it sounds using ordinary English spelling (Niamh becomes "Neev", Siobhan becomes "Sheh-vawn"), add hyphens to split syllables it runs together, write numbers and acronyms as words ("twenty-four seven", "D-J"), and set the vocal language to match the lyric. Test the single line before regenerating the whole song.

This guide is for anyone whose lyric includes a word the AI does not say the way they do: a person's name, a hometown, a pet, a band, a brand, a slang term, a word borrowed from another language. It is the most common complaint after a first generation from a lyrics-to-song generator, and it is nearly always fixable in a minute.

You will get a method for diagnosing what went wrong, a respelling reference for tricky name patterns, techniques for stress and syllable splits, and a short test routine that avoids burning credits on full-length takes.

Why AI singers get words wrong

A singing model turns written text into sound. For common words, the mapping from spelling to pronunciation is well learned. For names, slang, brands and borrowed words, the model has seen fewer examples, and English spelling is notoriously inconsistent. "Ough" alone sounds different in "though", "through", "tough" and "bough". Faced with an unfamiliar word, the model makes its best guess from the letters.

Singing makes errors more noticeable than speech. Vowels are stretched over long notes, so a wrong vowel lasts for a full beat or more. Stress can be pushed around by the melody, so a name stressed on the second syllable might be sung with stress on the first if that is where the strong beat falls.

There are four distinct failure types, and each has a different fix:

The respelling method

1. Say the word slowly and split it

   Break it into syllables as you say it: Sio-bhan becomes 'sheh' and 'vawn'.

2. Write each syllable with the most common English spelling

   Use patterns English speakers read the same way every time: 'ee' as in see, 'ay' as in day, 'oh' as in go, 'oo' as in moon, 'ai' as in rain, 'ow' as in now.

3. Join or hyphenate

   If the model ran syllables together before, keep the hyphen: 'Sheh-vawn'. If it split them oddly, try joining: 'Shevawn'.

4. Test the line alone

   Generate a short take with just the verse or chorus that contains the word. Listen only to that word.

5. Iterate once or twice

   If it is close but not right, change one letter group at a time. 'Shevawn' to 'Shuh-vawn' changes only the first vowel.

Respelling reference for common tricky patterns

These are suggestions to try first, written for an English vocal. Pronunciations vary by person and region, so always use the version the person or place actually uses.

For birthday songs specifically, where the name carries the whole hook, our guide on whether AI can sing unusual names goes deeper into name patterns, and happy birthday songs with a name shows where to place the name in the melody.

Stress: when the sounds are right but the emphasis is wrong

English stress matters. "PRE-sent" (a gift) and "pre-SENT" (to show) are spelled the same. In singing, the melody tends to put weight on whatever syllable lands on a strong beat. If your three-syllable name is stressed on the second syllable but the line starts it on the downbeat, the first syllable gets the weight.

Capitalizing a syllable ("ber-NA-dette") is sometimes suggested, but in our experience it is not a reliable control; some generations ignore it and some may treat capitals oddly. More reliable fixes:

• Add a pickup word before the name. "Oh, Bernadette" or "My Bernadette" shifts the name later, often moving its stressed syllable onto the beat.
• Move the name to the end of the line. Line endings are usually held, and the model tends to stress the last strong syllable of a line naturally.
• Use a shorter form. "Bernie" or "Dette" has fewer stress options to get wrong.
• Respell to imply stress. Doubling a consonant or lengthening a vowel can nudge emphasis: "Ber-nuh-DETT" reads more naturally with the final stress than "Bernadette".

Slang, brand words and borrowed words

Slang usually works if it is spelled the way it is commonly written online, because that is how the model has seen it. "Gonna", "wanna", "y'all" and "ain't" are generally fine. Very new or very local slang is less predictable; respell it like a name.

Brand and product names often have invented spellings. Spell them as they sound: a brand stylized with unusual capitals or numbers should be written as plain words. If you are making a jingle, the guide on writing jingle lyrics covers how to place the brand name so it lands clearly. Note that using someone else's brand in a song may raise trademark questions; check before using it commercially.

Words from another language inside an English lyric are the hardest case. If a Spanish word appears once in an English song, an English-set vocal will tend to anglicize it. You can respell it ("corazón" as "kor-ah-SOHN"), or, if the song uses a lot of the other language, consider setting the vocal language to that language for the sections where it dominates. The full approach is in can AI sing a song in two languages.

Numbers, acronyms and symbols

These cause trouble because the same characters can be read several ways. Always write them exactly as they should be sung.

Acronyms pronounced as words, like NASA or SCUBA, are usually fine as written, because the model has seen them used as words many times. Acronyms pronounced as letters need hyphens or spaces.

The language setting

MusicVivo supports 10 vocal languages. The language setting tells the singer which pronunciation rules to apply. An English lyric with the vocal language set to something else will usually sound accented or wrong, and the reverse is also true. Before respelling anything, confirm the language matches the lyric. Many "pronunciation problems" in non-English songs disappear once this is set correctly. The broader guide on making an AI song in another language covers language choice in depth.

Respelling in lyrics that are not in English

The method is the same in other languages, but you respell using that language's own reliable patterns, not English ones. In a Spanish lyric with the vocal language set to Spanish, an English name like "Michael" might come out with Spanish vowels. Respell it with Spanish spelling for the sound you want, for example "Maikol", because the singer is now applying Spanish rules. In a German lyric, "sch" reliably gives the "sh" sound and "ei" gives "eye". In Italian, "chi" gives "kee" and "gli" gives a soft "ly" sound.

The general rule: write the word as a native speaker of the lyric's language would spell that sound if they had never seen the original. If you do not speak the language well, ask someone who does to read your respelling aloud. If it sounds right in their mouth, it will usually sound right in the singer's.

When to change the word instead

Respelling is not always the best answer. Sometimes a word is hard to sing for reasons that have nothing to do with the AI. Long Latin-derived words with many unstressed syllables, like "particularly" or "responsibility", are awkward for human singers too. Clusters of consonants, like "sixths" or "glimpsed", trip any voice at speed. Words whose meaning depends on a subtle stress difference can be misheard even when sung perfectly.

Ask two questions before you respell. Is this word essential, such as a name, a place or a promise? Then fix it. Is it decorative, a word you chose because it sounded clever on paper? Then consider swapping it for a simpler synonym. "Particularly" can usually become "most of all"; "responsibility" can become "the weight". The line often gets better, not just easier.

There is also a middle path for essential words: keep the name but give it room. A name squeezed into a fast run of syllables is far more likely to be mangled than the same name held on a long note at the end of a line. Shorten the words around it, and the singer has time to land every sound. Our guide on fixing syllable count covers the trimming techniques that create that space.

A test routine that saves credits

Credits are seconds of audio, so testing a 15-second section costs far less than regenerating a three-minute song. Build a test lyric that contains only the section with the problem word:

Generate it with the same genre, tempo and vocal as your full song, so the melody treats the word in a similar way. Listen only to the problem word. When it sounds right, put the respelling into the full lyric and generate the complete track.

On the Free plan, tracks are capped at 30 seconds, which is exactly the length you need for a pronunciation test.

Worked example: a memorial song with three hard names

A user wrote a tribute song naming a grandmother, Gráinne, her hometown, Dún Laoghaire, and a family dog, Xolo. The first generation sang "Grain-ee", "Dun La-og-hair-ee" and "Zoh-loh".

Fixes:

• Gráinne, intended "GRAWN-ya": respelled "Grawn-ya". Correct on the first retry.
• Dún Laoghaire, intended "dun LEER-ee": respelled "Dun Leery". Correct on the first retry.
• Xolo, intended "SHOH-loh": respelled "Sho-lo". The first retry gave "Shoe-lo"; changing to "Show-low" fixed it.

Total cost: three 20-second tests and one full song. The writer then corrected the spellings in the .lrc file before making a lyric video. If you are writing a tribute, our memorial tribute song guide covers tone and structure.

People also ask

Why does AI mispronounce words when singing? It guesses sounds from spelling, and names, slang and borrowed words often break normal spelling patterns. Singing stretches vowels and moves stress, which makes errors more audible.

How do I make AI sing a name correctly? Respell it the way it sounds with common English patterns, hyphenate if syllables blur, keep the vocal language matched, and test the single line first.

Will phonetic spelling show up in my lyric file? Yes, the lyric file shows what you pasted. It is plain text, so you can fix the spelling afterwards without changing the timing.

How do I get AI to sing an acronym or a number? Write it as it should be sung: letters with hyphens like "D-J", and numbers as words like "nineteen ninety-nine".
