Create a custom vocabulary

Creates a new custom vocabulary configuration to improve transcription accuracy.

Custom vocabularies are used to enhance speech-to-text transcription by providing:

• Specific phrases that are commonly used in your domain
• Phonetic representations (“sounds like”) to help the system recognize these phrases

For example, you might define:

• Phrase: “IEEE”
• Sounds Like: [“I triple E”]

This helps the system correctly transcribe technical terms, brand names, or industry-specific terminology.

The API returns immediately, but the transcription service can take up to 1 minute to incorporate the custom vocabulary change.
