# Azure AI Speech Transcription for Python

## When to Use

- Transcribe an authorized audio file with the `azure-ai-transcription` client.
- Review timestamped output and options supported by the installed SDK version.
- For streaming or asynchronous batch jobs, select the appropriate Speech API instead.

## Prerequisites

Use a project-pinned SDK in an isolated Python environment. Confirm the Speech
resource, endpoint, permissions, audio consent, cost and retention before upload.
Do not log keys, audio contents, or full transcripts by default.

## File Example

```python
import os
from azure.core.credentials import AzureKeyCredential
from azure.ai.transcription import TranscriptionClient
from azure.ai.transcription.models import TranscriptionContent, TranscriptionOptions

client = TranscriptionClient(
    endpoint=os.environ["TRANSCRIPTION_ENDPOINT"],
    credential=AzureKeyCredential(os.environ["TRANSCRIPTION_KEY"]),
)
with client:
    with open("audio.wav", "rb") as audio:
        result = client.transcribe(TranscriptionContent(
            definition=TranscriptionOptions(locales=["en-US"]), audio=audio,
        ))
# Inspect result locally; handle empty output and service errors explicitly.
```

## Authentication and API Boundary

`DefaultAzureCredential` is also supported when the identity has the required
resource role. The previous `begin_transcription` and `begin_stream_transcription`
examples did not match this client. Do not invent a streaming adapter.

## Example Request

“Transcribe this consented local recording; keep the transcript private.”

## Limitations

Verify installed signatures and service limits against [Microsoft's SDK guide](https://learn.microsoft.com/en-us/python/api/overview/azure/ai-transcription-readme?view=azure-python).
This illustration has not contacted Azure; availability, accuracy and costs require
verification in the authorized environment.
