Introducing New Summarization

We're excited to announce the release of our first domain-specific language model (DSLM) for speech summarization of call center interactions.

You can request our new Summarization API endpoint by adding a summarize parameter set to v2 in the API call. It will then return a summary object in the response body of the output. The summary object includes status and a concise summary of the entire conversation.

The URL query to call the DSLM-powered Summarization API might look like this:

https://api.deepgram.com/v1/listen?summarize=v2

Example curl request:

You can send requests to the API with an Authorization header that references your project's API key

  • Authorization: Token YOUR_DEEPGRAM_API_KEY

The output response will contain the generated summary based on the provided audio. Summarization V2 supports English and Pre-Recorded audio.

Primary difference between V1 (summarize=true) and V2 (summarize=v2)

  • V1 provides summaries per channel. V2 provides a single summary across all the channels.

  • V1 response contains summary objects (with summary, start, and end word). V2 response contains a single object with result and short key.

We are thrilled to get this feature into your hands and await your feedback. Please share it with us at Product Feedback or your dedicated support channel.
