# Align speech

> Aligns a known transcript to an audio file.

`elevenLabs.alignSpeech` requires `file` and its exact `text`. It returns timed `words` and `characters` plus the provider's alignment `loss` score.

```ts automations/align-speech.automation.ts theme={null}
import { automation, markSignificant, onInvocation } from "automate.ax"
import { elevenLabs } from "automate.ax/elevenlabs"

export default automation("Align speech", () => {
  const request = onInvocation<{ audio: File }>()
  markSignificant(
    elevenLabs.alignSpeech({ file: request.audio, text: "Welcome aboard." }),
  )
})
```
