+# Speech Gateway
+
+Thin HTTP gateway that rewrites simple STT/TTS requests into the multipart oneshot format expected by a StreamKit backend.
+
+## Prereqs
+
+- StreamKit server running locally (default assumed: `http://127.0.0.1:4545`).
+- Go 1.24+.
+
+## Run the gateway
+
+```sh
+cd examples/streamkit-cli-gateway
+go run ./cmd/gateway --listen :8080 --skit-url http://127.0.0.1:4545
+```
+
+Environment equivalents:
+
+- `GATEWAY_LISTEN` (default `:8080`)
+- `SKIT_URL` (default `http://127.0.0.1:4545`)
+- `SKIT_TOKEN` (optional bearer sent to Skit)
+- `GATEWAY_MAX_CONCURRENCY` (default 10)
+- `GATEWAY_MAX_BODY_BYTES` (default 10MB)
+
+## STT via curl (Ogg/Opus)
+
+Transcribe a file:
+
+```sh
+curl -H "Content-Type: audio/ogg" --data-binary @speech.ogg http://127.0.0.1:8080/stt
+```
+
+Transcribe from microphone (requires ffmpeg):
+
+```sh
+./stt.sh
+```
+
+Press Ctrl-C when done speaking. The script captures audio, sends it to the gateway, and displays the transcription.
+
+Response is NDJSON (one JSON object per line).
+
+## TTS via curl (plain text)
+
+```sh
+curl -H "Content-Type: text/plain" --data 'Hello from StreamKit' http://127.0.0.1:8080/tts | ffplay -nodisp -autoexit -
+```
+
+Response is `audio/ogg` (Opus mono).
