### Create and start a dubbing job with SarvamAI SDK

Source: https://docs.sarvam.ai/api/api-guides-tutorials/dubbing/overview

Install the SDK with `pip install sarvamai`, set `SARVAM_API_KEY`, and point `media` at a local file. The client resolves the dubbing endpoint from its default environment, so your API key is the only configuration it needs. The job runs after calling `start`; see the Job Lifecycle guide for the polling loop.

```python
import os
from pathlib import Path
from sarvamai import SarvamAI

client = SarvamAI(api_subscription_key=os.environ["SARVAM_API_KEY"])

media = Path("sample.mp4")

created = client.dubbing.create(
    source_language_code="en-IN",
    target_language_codes=["hi-IN", "ta-IN"],
    export_options=["video", "srt"],
    voice_cloning=True,
    num_speakers=1,
    job_name=media.name,
)

client.dubbing.upload(created.data.upload_url, media)
client.dubbing.start(job_id=created.data.job_id)

print(created.data.job_id)
```

--------------------------------

### Python: Create, upload, and start document translation job

Source: https://docs.sarvam.ai/api/api-guides-tutorials/doc-translation/overview

Install the SDK with `pip install sarvamai`, set `SARVAM_API_KEY`, and point `document` at a local PDF or Office file. The client uses `https://api.sarvam.ai` by default. After `create`, `PUT` the file bytes to `upload_url` with `Content-Type` and `x-ms-blob-type: BlockBlob`, then call `start`. Polling and export are covered in the Poll and Export guide.

```python
import os
from pathlib import Path

import httpx
from sarvamai import SarvamAI

client = SarvamAI(api_subscription_key=os.environ["SARVAM_API_KEY"])
document = Path("chapter1.pdf")

# 1. Create job (job_name is optional: defaults to original_filename)
job = client.document_translation.create(
    job_name="chapter1",
    source_language_code="en-IN",
    target_language_codes=["hi-IN", "ta-IN"],
    original_filename=document.name,
)

# 2. Upload to the signed URL (required: not handled by the SDK)
with document.open("rb") as f:
    httpx.put(
        job.upload_url,
        content=f.read(),
        headers={
            "Content-Type": "application/pdf",
            "x-ms-blob-type": "BlockBlob",
        },
        timeout=120.0,
    )

# 3. Start the pipeline
client.document_translation.start(job_id=job.job_id)

# 4–5. Poll translation, then export: see Poll and Export guide
print(job.job_id)
```

### JavaScript: Create, upload, and start document translation job

Source: https://docs.sarvam.ai/api/api-guides-tutorials/doc-translation/overview

Install the SDK with `npm install sarvamai`, set `SARVAM_API_KEY`, and point `document` at a local PDF or Office file. The client uses `https://api.sarvam.ai` by default. After `create`, `PUT` the file bytes to `upload_url` with `Content-Type` and `x-ms-blob-type: BlockBlob`, then call `start`. Polling and export are covered in the Poll and Export guide.

```javascript
import fs from "fs";
import { SarvamAIClient } from "sarvamai";

const client = new SarvamAIClient({
    apiSubscriptionKey: process.env.SARVAM_API_KEY,
});

const documentPath = "chapter1.pdf";

// 1. Create job (job_name is optional, defaults to original_filename)
const job = await client.documentTranslation.create({
    job_name: "chapter1",
    source_language_code: "en-IN",
    target_language_codes: ["hi-IN", "ta-IN"],
    original_filename: documentPath,
});

// 2. Upload to the signed URL (required, not handled by the SDK)
await fetch(job.upload_url, {
    method: "PUT",
    headers: {
        "Content-Type": "application/pdf",
        "x-ms-blob-type": "BlockBlob",
    },
    body: fs.readFileSync(documentPath),
});

// 3. Start the pipeline

venv\Scripts\activate
pip install -r requirements.txt
```

--------------------------------

### PHP Guzzle GET request for live status

Source: https://docs.sarvam.ai/api-reference/creative-agents-dubbing/live-status

PHP example using GuzzleHttp client to fetch live status. Requires Guzzle installed via Composer.

```php
<?php
require_once('vendor/autoload.php');

$client = new \GuzzleHttp\Client();

"Build a translator app that converts English to Kannada using Sarvam's API."
```

--------------------------------

### Correct and Incorrect Start Strategy Ordering

Source: https://docs.sarvam.ai/api/integration/pipecat-production-guide

Strategy order matters: first match wins. The wrong example has MinWords as dead code because External claims the turn on speech-start before any transcript exists. The right example picks one strategy for lowest latency or word gating.

```python
# WRONG: min_words is dead code. External claims the turn on speech-start,
# before any transcript exists.
start=[ExternalUserTurnStartStrategy(), MinWordsUserTurnStartStrategy(min_words=3)]
```

```python
# RIGHT: pick one. External for lowest latency, or MinWords alone to gate on words.
start=[MinWordsUserTurnStartStrategy(min_words=3, use_interim=True)]
```

--------------------------------

Teaching approach:
- Start with the basics and build up to complex concepts
- Use real-world examples and analogies to explain abstract concepts
- Break down complex problems into smaller, manageable steps
- Encourage students and praise their efforts
- Ask questions to check understanding
- Adapt your explanations based on the student's level
- Use simple language and avoid overwhelming with jargon
- When solving numerical problems, show each step clearly

Communication style:
- Be patient, encouraging, and supportive
- Speak clearly and at a moderate pace
- Celebrate small victories and correct mistakes gently
- If a student is struggling, try a different explanation approach
- Make learning interesting by connecting it to everyday life
