whisper-realtime-stt

whisper-realtime-stt is a skill for Claude Code, Codex from Seeed-Projects/Seeed-Jetson-DevelopTool. It costs 65 tokens per session (800 once invoked), scanned B, original, MIT.

A local speech-to-text setup using OpenAI Whisper on a Jetson computer. Speech-to-text converts spoken words from a USB microphone into written text in real time.

In plain words
What is it for?
Installing Whisper and its dependencies, configuring a USB microphone, testing the environment, and running real-time transcription on Jetson Orin.
Why use it?
It lets audio be transcribed directly on the device instead of requiring a network service. The guide also checks the audio environment and explains how Whisper compares with NVIDIA Riva.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 38
    Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.
    Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

whisper-realtime-stt scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Real-Time Speech-to-Text with Whisper on Jetson Orin

Deploy Whisper on Jetson Orin for real-time speech-to-text processing directly on-device, eliminating network dependency and enhancing privacy. Uses a USB microphone for audio input.


Execution model

Run one phase at a time. After each phase:

  • Relay all output to the user.
  • If output contains [STOP] → stop immediately, consult the failure decision tree.
  • If output ends with [OK] → tell the user "Phase N complete" and proceed to the next phase.

Prerequisites

Requirement Detail
Jetson device reComputer or other Jetson Orin-based device
Microphone reSpeaker Mic Array v2.0 or other USB microphone
JetPack With CUDA support
Network Internet access for cloning repo and installing packages

Phase 1 — Install dependencies (~5 min)

git clone https://github.com/LJ-Hao/Deploy-Whisper-on-NVIDIA-Jetson-Orin-for-Real-time-Speech-to-Text.git
cd Deploy-Whisper-on-NVIDIA-Jetson-Orin-for-Real-time-Speech-to-Text
pip install -r requirements.txt
sudo apt update && sudo apt install ffmpeg

Configure the microphone sample rate:

arecord -D hw:2,0 --dump-hw-params

[OK] when all packages install and ffmpeg is available. [STOP] if pip or apt install fails.


Phase 2 — Test environment (~1 min)

python test.py

Verify ffmpeg is installed:

ffmpeg -version

[OK] when test.py prints successful library import messages and ffmpeg -version shows version info. [STOP] if imports fail or ffmpeg is not found.


Phase 3 — Run real-time speech-to-text

python main.py

Speak into the microphone and observe real-time transcription output.

[OK] when transcription appears in the terminal as you speak. [STOP] if audio device errors or model loading fails.


Failure decision tree

Symptom Action
pip install -r requirements.txt fails Check Python version ≥ 3.8. Try pip install --upgrade pip first.
ffmpeg not found after install Run sudo apt install ffmpeg again. Verify with which ffmpeg.
arecord — no soundcard found Check USB microphone connection. Run arecord -l to list devices. Adjust device ID (hw:X,0).
test.py import errors Re-run pip install -r requirements.txt. Check for missing system libraries.
main.py — CUDA out of memory Close other GPU processes. Use a smaller Whisper model variant.
main.py — no audio input Verify microphone with arecord -D hw:2,0 -f S16_LE -r 16000 -d 5 test.wav.
Poor transcription accuracy Ensure microphone sample rate is 16000 Hz. Reduce background noise.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

whisper-realtime-stt is a skill published in the GitHub repository Seeed-Projects/Seeed-Jetson-DevelopTool (54 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 800 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
