Updated Nova-2 Model (English, Pre-recorded) - Improved Word Recognition

Natalie Rutgers

model = nova-2 Deepgram has done additional training to our Nova-2 General Model for English to improve accuracy for pre-recorded transcription, specifically addressing an issue with missing words / phrases. We intend to roll out similar updates for streaming transcription and across other Nova-2 tier models over the next two weeks. There should be no code changes required on your end - all requests with model=nova-2 will automatically get the latest version with the fix applied. For On-Premises customers, please reach out to your Deepgram contact if you'd like to update your models.

Improvements to Language Detection

Deepgram now offers the ability to restrict which languages will be detected by Deepgram's language detection algorithm. If you currently use the detect_language=true feature of Deepgram but your audio files are, for example, only in English and Spanish, you can improve the accuracy of your results by restricting which languages will be detected. Here's an example of how to restrict the detectable languages to only English ( en ) and Spanish ( es ): curl \ --request POST \ --header 'Authorization: Token YOUR_DEEPGRAM_API_KEY' \ --header 'Content-Type: audio/wav' \ --data-binary @youraudio.wav \ --url 'https://api.deepgram.com/v1/listen?detect_language=en&detect_language=es' This functionality is available for pre-recorded audio and Deepgram's models (not Whisper). For more information, head over to our developer documentation .

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: curl --location --request POST 'https://api.deepgram.com/v1/listen?summarize=v2' \ --header 'Authorization: Token <Your API KEY>' \ --header 'Content-Type: audio/wave' \ --data-binary '@/Path to file' 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. V2 of our Summarization offers improved performance in terms of quality, content, and readability of generated summaries. For the best results moving forward, we recommend leveraging V2 of our summarization. Learn more about using our new Summarization V2 feature. Test Summarization V2 using our API Playground. 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.
