aws-deepgram-sagemaker

Automation scripts for testing Deepgram services running on Amazon SageMaker as an "Endpoint" resource.

Speech-to-Text (STT)

JavaScript

See js-stt/README.md for setup and usage. Built on the AWS SDK HTTP/2 bidirectional streaming client (@aws-sdk/client-sagemaker-runtime-http2); configuration (region, endpoint name, input file, query string) is edited inline at the top of each script.

Scripts:

• stt.file.ts — streams a WAV file to a bidirectional streaming endpoint, chunking the file with keepalives
• stt.microphone.ts — captures live microphone input and streams it to a bidirectional streaming endpoint
• stress-stt.ts — fires N parallel stt.file.ts invocations and reports success/failure counts and timing

Python

See python-stt/README.md for full setup and usage.

Scripts:

• stt_microphone_stress.py — streams live microphone audio; supports multiple simultaneous connections
• stt_wav_stress.py stream — streams a WAV file at real-time pace; repeatable load testing without a microphone
• stt_wav_stress.py batch — posts WAV files via HTTP with configurable concurrency; reports latency and throughput
• stt_wav_async.py — transcribes a WAV file (up to 1 GiB) via the SageMaker InvokeEndpointAsync API with S3 input/output; suits long-form audio beyond the synchronous invoke limit, with configurable concurrency and a latency/throughput summary

Java

See java/README.md for an index of Java projects.

• java/stt/aws-sdk — WAV streaming load test built directly on AWS SDK v2 HTTP/2 bidi streaming
• java/stt/deepgram-sdk — same load test, via the Deepgram Java SDK + SageMaker transport

Text-to-Speech (TTS)

JavaScript

TBD

Python

See python-tts/README.md for full setup and usage.

Scripts:

• tts_stress.py — streams text phrases to multiple simultaneous bidirectional connections; plays audio from one selectable connection

---

Flux (Conversational STT)

Python

See python-flux/README.md for full setup and usage.

Scripts:

• flux_stress.py file — streams a WAV file to multiple Flux connections at real-time pace
• flux_stress.py microphone — streams live microphone audio to multiple Flux connections
• flux_stress.py list-endpoints — lists available SageMaker endpoints in the target region
