# Premove ITN supported forms

> Structured values and English spoken forms supported by Premove ITN.

Premove ITN targets English structured values commonly used by voice agents.
The table shows valid written candidates. The contextual scorer can leave a
phrase unchanged or select another candidate when the sentence supports it.

| Form                     | Spoken                              | Written               |
| ------------------------ | ----------------------------------- | --------------------- |
| Numbers                  | `one hundred twenty`                | `120`                 |
| Digit sequences          | `zero eight two zero six three`     | `082063`              |
| Times                    | `four thirty`                       | `04:30`               |
| Dates                    | `march fifth twenty twenty four`    | `march 5 2024`        |

| Decimals                 | `one point five`                    | `1.5`                 |
| Measurements             | `two hundred meters`                | `200 m`               |
| Ordinals                 | `the eighth`                        | `8th`                 |
| Phone numbers            | `eight one four two three one four` | `814-2314`            |
| Email addresses and URLs | `support at example dot com`        | `support@example.com` |
| Versions and identifiers | `v three dot one dot nine`          | `v3.1.9`              |
| Punctuation              | `comma`                             | `,`                   |
| Approved abbreviations   | `doctor`                            | `dr.`                 |

The deterministic Rust layer exposes 13 candidate kinds: `DIGIT_SEQUENCE`,
`CARDINAL`, `TIME`, `DATE`, `MONEY`, `DECIMAL`, `PHONE`, `ELECTRONIC`,
`MEASUREMENT`, `ORDINAL`, `PUNCTUATION`, `WHITELIST`, and `WORD`.

## Current boundaries

Premove ITN does not provide first-class normalization for non-English speech,
street addresses, free-form rewriting, or arbitrary application-specific
formats. Text remains unchanged when the decoder does not select a candidate.
The model cannot create a written form that the Rust candidate layer did not
offer. If an application requires a stricter output schema, validate the
result before passing it to a tool.

For the exact accepted grammar and edge cases, see
[Rust candidate coverage](/itn/docs/internals/rust-candidate-coverage).
