Arbitrary key-value pairs that are attached to the API response for usage in downstream processing

Recognizes the sentiment throughout a transcript or text

Summarize content. For Listen API, supports string version option. For Read API, accepts boolean only.

Label your requests for the purpose of identification during usage reporting

Detect topics throughout a transcript or text

Custom topics you want the model to detect within your input audio or text if present Submit up to `100`.

Sets how the model will interpret strings submitted to the `custom_topic` param. When `strict`, the model will only return topics submitted using the `custom_topic` param. When `extended`, the model will return its own detected topics in addition to those submitted using the `custom_topic` param

Recognizes speaker intent throughout a transcript or text

Custom intents you want the model to detect within your input audio if present

Sets how the model will interpret intents submitted to the `custom_intent` param. When `strict`, the model will only return intents submitted using the `custom_intent` param. When `extended`, the model will return its own detected intents in the `custom_intent` param.

Identifies and extracts key entities from content in submitted audio

Identifies the dominant language spoken in submitted audio

Deprecated: use `diarize_model` instead. Recognize speaker changes. Each word in the transcript will be assigned a speaker number starting at 0.

Select and enable a specific diarization model version. Specifying this parameter enables diarization and selects the model — you do not need to also set the deprecated `diarize=true` parameter. For batch, supported values are `latest` (currently v2), `v1`, and `v2`. For streaming, supported values are `latest` (currently v1) and `v1`; `v2` returns a validation error on streaming requests.

Filler Words can help transcribe interruptions in your audio, like "uh" and "um"

Key term prompting improves recognition of specialized terminology and brands. Only compatible with Nova-3. `keyterm` accepts plain terms only. Unlike the legacy `keywords` feature, it does not support weights or intensifiers. Appending one (for example, `keyterm=term:0.15`) is not rejected—the weight is silently ignored and the entire value is treated as a literal keyterm. To boost multiple separate keyterms, repeat the `keyterm` parameter (for example, `keyterm=term1&keyterm=term2`). To boost one multi-word phrase as a single keyterm, join the words with `%20` or `+` (for example, `keyterm=customer%20service`). Do not separate keyterms with commas, semicolons, or line breaks.

Keywords can boost or suppress specialized terminology and brands. `keywords` is not supported with Nova-3 models; use `keyterm` instead.

The [BCP-47 language tag](https://tools.ietf.org/html/bcp47) that hints at the primary spoken language. Depending on the Model and API endpoint you choose only certain languages are available
