# Set your transcription language

> Choose the language Tella transcribes your videos in, and teach it names and terms it keeps getting wrong.

Tella transcribes your videos to power subtitles, transcript editing, and search. The **Language** settings page is where you set which language it transcribes in, and where you teach it words it would otherwise misspell.

To open it, click your avatar, go to **Settings**, then **Language** under **Account**.

## Transcription language

**Transcription language** chooses the language used for your videos' subtitles. Set it to the language you actually speak in — not the language you want subtitles translated into.

This is your personal default and applies to videos you record from now on. It does not re-transcribe videos you have already recorded.

<Tip>
  Already recorded a video in the wrong language? You do not need to record it again — [re-transcribe it](/docs/help/editing/retranscribe-a-video) from the editor and pick the correct language there.
</Tip>

## Transcription dictionary

The dictionary teaches transcription the words it cannot guess: people's names, your product and company names, and technical jargon.

Add each term using the exact spelling and capitalization you want to see in the transcript. Do not add ordinary everyday words — the model already knows those, and padding the dictionary makes it less accurate, not more.

<Note>
  The transcription dictionary is available in English, Spanish, Portuguese, French, German, and Italian.
</Note>
