## Evaluation Prompt

````text

# Task
Using https://docs.speechmatics.com/, complete the following task:

Using the Speechmatics Python SDK, build me a script that transcribes a sample audio file:

1. Install the official Speechmatics Python SDK (pip install)
2. Transcribe this audio file and print the transcribed text:
   https://storage.googleapis.com/aai-web-samples/5_common_sports_injuries.mp3
3. If the SDK expects a local file, download the audio first
4. Print the transcription to stdout

You MUST use the official Speechmatics Python SDK — do not make raw HTTP/REST calls. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
