Install Jentic One Beta

Connect the Amazon Transcribe to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Amazon Transcribe, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

For Agents

Transcribe recorded audio to text with optional speaker diarisation, custom vocabulary, redaction, and call-analytics enrichment so an agent can read what was said in a meeting, support call, or clinical encounter.

Use for: I want to transcribe a recorded customer support call, Start a medical transcription job for a clinician dictation, Create a custom vocabulary for product names, Redact sensitive PII from a transcript using a vocabulary filter

Not supported: Does not handle text-to-speech, real-time translation of arbitrary text, or voice cloning - use for converting recorded audio into transcripts (with optional medical or call-analytics enrichment) only.

Use Cases

Patterns agents use Amazon Transcribe API for, with concrete tasks.

★ Contact-Centre Call Analytics

Run Call Analytics transcription jobs against recorded support calls to get speaker-diarised transcripts with sentiment per speaker, talk-time ratios, non-talk time, interruptions, and category matches against rules you define (e.g. 'mentions cancellation'). StartCallAnalyticsJob accepts an S3 URI, an output location, and a list of CategoryNames; the resulting JSON powers QA dashboards and agent coaching workflows.

Call StartCallAnalyticsJob with CallAnalyticsJobName 'support-2026-06-09-call-42', Media.MediaFileUri s3://calls/2026-06-09/call-42.wav, OutputLocation s3://calls-out/, and ChannelDefinitions for AGENT and CUSTOMER.

Clinical Dictation Transcription

Amazon Transcribe Medical converts clinician dictations into structured text optimised for medical vocabulary. StartMedicalTranscriptionJob accepts the audio, a Specialty (e.g. PRIMARYCARE), a Type (CONVERSATION or DICTATION), and an output bucket; the resulting transcript can be fed into an EHR. The service supports content identification (PHI) for downstream redaction.

Call StartMedicalTranscriptionJob with MedicalTranscriptionJobName, Specialty 'PRIMARYCARE', Type 'DICTATION', Media.MediaFileUri pointing at the dictation audio, and OutputBucketName.

Domain-Specific Custom Vocabularies

Improve recognition of brand names, drug names, or technical jargon by creating a CustomVocabulary (a flat term list) or a CustomLanguageModel (trained on representative transcripts). CreateVocabulary uploads phrases; CreateLanguageModel kicks off training against your S3 training data. Reference the resulting names in StartTranscriptionJob.Settings to apply them to a specific job.

Call CreateVocabulary with VocabularyName 'product-names-v3', LanguageCode 'en-US', and Phrases listing your product catalogue, then reference VocabularyName in subsequent StartTranscriptionJob calls.

Agent-Driven Meeting Note Generation via Jentic

An assistant agent that turns recorded meetings into searchable notes can call Transcribe through Jentic without holding AWS keys. The agent submits an intent like 'transcribe this meeting recording with speaker labels'; Jentic loads StartTranscriptionJob with ShowSpeakerLabels enabled, executes it, and polls GetTranscriptionJob until the TranscriptFileUri is ready. The agent then summarises the transcript with its language model.

Through Jentic, search for 'transcribe an audio file with speaker labels', load StartTranscriptionJob, execute with Media.MediaFileUri, MediaFormat, LanguageCode, and Settings.ShowSpeakerLabels=true.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your AWS access keys are stored once, encrypted, by your own Jentic One instance and used to sign each Transcribe request with SigV4 at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'transcribe an audio file with speaker labels' or 'get a transcription job status', and Jentic returns the matching Transcribe operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Amazon Transcribe API through Jentic.

Why is there no official OpenAPI spec for Amazon Transcribe?

AWS does not publish an OpenAPI specification for Amazon Transcribe; it ships Smithy models and language-specific SDKs instead. Jentic generates and maintains this OpenAPI spec so that AI agents and developers can call Amazon Transcribe via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does Amazon Transcribe use?

Transcribe uses AWS SigV4 with X-Amz-Target identifying the action (e.g. Transcribe.StartTranscriptionJob). The IAM principal also needs s3:GetObject on the input audio and s3:PutObject on the output bucket. Through Jentic, your AWS keys are vaulted and Jentic computes the SigV4 signature for each call.

Can I get speaker labels with Transcribe?

Yes. Set Settings.ShowSpeakerLabels=true and Settings.MaxSpeakerLabels in StartTranscriptionJob, or use ChannelDefinitions for stereo recordings where each channel is a known participant. Call Analytics jobs always produce speaker-diarised output with AGENT and CUSTOMER labels.

What are the rate limits for Amazon Transcribe?

Default per-region quotas are typically 100 concurrent batch jobs, audio up to 4 hours and 2GB per file, and a few transactions per second on the management APIs (CreateVocabulary, ListTranscriptionJobs, etc.). Streaming Transcribe has separate connection-level quotas.

How do I transcribe an audio file through Jentic?

Search Jentic with 'transcribe an audio file with speaker labels', load StartTranscriptionJob, and execute with TranscriptionJobName, Media.MediaFileUri, MediaFormat, LanguageCode, and OutputBucketName. Then load GetTranscriptionJob and poll until TranscriptionJobStatus is COMPLETED.

Can Transcribe redact sensitive information from a transcript?

Yes. ContentRedaction.RedactionType=PII removes US PII categories like name, address, and credit card. Custom VocabularyFilters can additionally remove arbitrary terms (e.g. competitor names) by setting Settings.VocabularyFilterMethod to 'mask' or 'remove'.

What languages does Transcribe support?

Standard Transcribe supports more than 30 languages including English variants, Spanish, French, German, Mandarin, Japanese, and Hindi. Medical Transcribe supports US English only. The exact LanguageCode value is required on every transcription job.

Can I limit what my agent is allowed to do with the Amazon Transcribe API?

Yes. Because Jentic One runs self-hosted, you decide which Transcribe operations your agent may call, and its access is limited to exactly those. Since Transcribe routes every action through a single endpoint by X-Amz-Target rather than by resource paths, you scope at the operation level, for example allowing StartTranscriptionJob and GetTranscriptionJob so the agent can submit and poll jobs. Management operations such as CreateVocabulary or CreateLanguageModel stay out of reach unless you explicitly add them, and your AWS keys are held by your own instance rather than exposed to the agent.
