How to Use Custom Lyrics in Udio AI: Full Step-by-Step Guide
To use custom lyrics in Udio AI, switch the lyrics option to Custom in the creation panel and input the text formatted with brackets like [Verse] and [Chorus].
Udio AI has transformed AI music generation by giving creators the ability to produce complete songs with highly realistic vocals. Writing custom lyrics is the key to creating original tracks that stand out, rather than relying on automatic generation.
Activating the Custom Lyrics Mode
The creation settings on Udio AI feature three modes for managing lyrics: Auto, Instrumental, and Custom. Choosing the Custom tab displays a text input box where one can type or paste original song lyrics.
This text box has a character limit that corresponds to the initial audio block generated by the model. Structuring the song in short sections is the best approach to stay within these limits.
Formatting Your Lyrics with Control Tags
The Udio AI text synthesizer relies on metatags enclosed in square brackets to recognize different musical sections. These tags guide the AI to sing in the appropriate style for each part of the track.
The table below highlights the most common structural tags used to format custom lyrics:
| Control Tag | Musical Function | Formatting Example |
|---|---|---|
| [Verse] | Indicates the narrative sections | [Verse 1] |
| [Chorus] | Marks the main hook of the song | [Chorus] |
| [Bridge] | Creates a transitional segment | [Bridge] |
| [Pre-Chorus] | Builds tension before the chorus | [Pre-Chorus] |
| [Outro] | Signals the end of the track | [Outro] |
Using Metatags for Vocal Effects
Creators can also use metatags to control vocal delivery styles and emotional tone. Placing these tags directly above the lyrics line changes how the vocalist performs the words.
[Spoken Word] tags instruct the model to speak the lines instead of singing. Other tags like [Whisper] or [Scream] add variety and dynamic range to the vocal performance.
Extending Your Songs with Long Custom Lyrics
Since the initial generation is limited to a short audio segment, the Extend feature must be used to compile a full-length song. Extending a track requires selecting where to attach the next section.
When selecting Add Section Before or Add Section After, a new Custom box becomes available. The next part of the lyrics must be written in this box without repeating previous text.
Common Mistakes to Avoid in Udio AI
Pasting a complete, multi-page lyric sheet into the initial generation box is a common mistake. The model will either ignore the later verses or speed up the singing style to fit everything in.
Neglecting line breaks is another mistake that causes unnatural vocal delivery. Splitting lyrics into short stanzas gives the model room to insert realistic breathing pauses.
DomineTec Tip: If the generator is skipping lines or mispronouncing words, add clear punctuation marks like commas and periods. This guides the engine to pause and articulate the text correctly.
Tips for Clear and Accurate Vocals
Defining the language in the prompt helps the engine select the correct phonetic model. Adding terms like [American English] or [British English] to the prompt ensures correct pronunciation.
Keeping the vocabulary simple and using predictable rhyme schemes improves vocal clarity. Simple structures allow the AI to focus on musical expression.
