Built by Metorial, the integration platform for agentic AI.
Verifies whether a speaker matches a previously enrolled voice profile. Compares the provided audio against the enrolled profile and returns a confidence score and accept/reject decision. Uses text-independent verification — the speaker can say anything.
Converts text into natural-sounding synthesized speech audio using Azure neural voices. Provide either plain text (which will be wrapped in SSML automatically) or custom SSML for fine-grained control over pronunciation, prosody, speaking styles, pauses, and other speech characteristics. Returns the synthesized audio as a base64-encoded string.
Retrieves the full list of available text-to-speech voices for the configured Azure Speech region. Use this to discover available voices, their supported languages, speaking styles, and capabilities before synthesizing speech. Results can be filtered by locale or gender.
Creates, retrieves, lists, or deletes speaker recognition profiles. Speaker profiles are used for voice verification (confirming identity) and identification (determining who is speaking). Supports text-independent speaker recognition profiles.
Identifies which speaker from a group of enrolled profiles is speaking in the provided audio. Compares the audio against up to 50 candidate speaker profiles and returns the best match with a confidence score. Uses text-independent identification — the speaker can say anything.
Performs real-time speech-to-text recognition on short audio (up to 60 seconds). Converts spoken audio into text using Azure's speech recognition engine. Optionally includes **pronunciation assessment** to evaluate the accuracy, fluency, completeness, and prosody of spoken audio against a reference text.
Lists available base speech-to-text models for all locales, including standard and Whisper models. Use this to discover model IDs for batch transcription.
Lists all batch transcription jobs in your Azure Speech resource. Returns summary information for each transcription including status, locale, and timestamps. Supports pagination for large result sets.
Submits a batch transcription job to process one or more audio files asynchronously. Ideal for transcribing large volumes of prerecorded audio. Provide audio file URLs or an Azure Blob Storage container URL. The job runs asynchronously — use the **Get Batch Transcription** tool to check status and retrieve results.
Deletes a batch transcription job and its associated result data. Use this to clean up completed transcriptions after retrieving their results, or to cancel transcriptions that are no longer needed.
Retrieves the status and details of a batch transcription job. When the transcription is complete, also fetches the result files including transcription output and report. Use this to check progress of a previously submitted batch transcription and to retrieve the final results.
