Why punjabi to english azure document translator not working.

Kumari, Reshmi (External) 0

We are trying to run azure AI document translator on Punjabi text pdf and output language as English. But translator service is returning error with details "The document does not have any translatable text". English to Punjabi translation is working good but not vice versa.

Hello Kumari, Reshmi (External),

The error message "The document does not have any translatable text" typically indicates that the Azure Document Translator is unable to detect text within the provided PDF for translation. This issue can arise due to several factors, here are some steps to consider,

Make sure the PDF is in a compatible format for translation. Digitally generated (native) PDFs work best, while scanned documents may cause issues with text recognition and formatting.

Refer this PDF format renders the best results.
The document might not contain recognizable or translatable text. If the text is embedded in images or is not clearly defined as text, the translation service may not be able to process it.

If the document contains multiple languages, the translation might not work as expected. The service may struggle to identify and translate the text correctly.
If the PDF contains image-based text, use an OCR tool to extract the text and generate a new PDF with selectable text before submitting it for translation.

Specifying the source language in your translation request can improve translation accuracy.

I hope this helps. And, if you have any further query do let us know.

Thank you!

Hi Kumari, Reshmi (External),

Could you please test this in the Custom Translator? I tried to reproduce the scenario in my environment, but it is working fine. Here is a sample code that you can use for testing.

import requests, uuid, json

# Add your key and endpoint
key = "
<your-translator-key>"
endpoint = "https://api.cognitive.microsofttranslator.com"

# location, also known as region.
# required if you're using a multi-service or regional (not global) resource. It can be found in the Azure portal on the Keys and Endpoint page.
location = "swedencentral"

path = '/translate'
constructed_url = endpoint + path

params = {
    'api-version': '3.0',
    'from': 'pa',
    'to': ['en']
}

headers = {
    'Ocp-Apim-Subscription-Key': key,
    # location required if you're using a multi-service or regional (not global) resource.
    'Ocp-Apim-Subscription-Region': location,
    'Content-type': 'application/json',
    'X-ClientTraceId': str(uuid.uuid4())
}

# You can pass more than one object in body.
body = [{
    'text': 'ਸਤ ਸ੍ਰੀ ਅਕਾਲ! ਤੁਸੀਂ ਕਿਵੇਂ ਹੋ? ਜੀ ਆਇਆ ਨੂੰ! ਅਸੀਂ ਤੁਹਾਡਾ ਸੁਆਗਤ ਕਰਦੇ ਹਾਂ। ਜੀਵਨ ਵਿੱਚ ਮਿਹਨਤ ਅਤੇ ਧੈਰਜ ਬਹੁਤ ਮਹੱਤਵਪੂਰਨ ਹਨ। ਜਿਹੜਾ ਬੀਜੇ ਬੋਹੜ, ਓਹ ਖਾਵੇ ਥੋਹੜ, ਇਸ ਮਤਲਬ ਹੈ ਕਿ ਅਸੀਂ ਜਿਹੋ ਜਿਹੀ ਮੇਹਨਤ ਕਰਦੇ ਹਾਂ, ਉਹੀ ਫਲ ਮਿਲਦਾ ਹੈ। ਮੈਂ ਅੱਜ ਬਹੁਤ ਖੁਸ਼ ਹਾਂ ਕਿਉਂਕਿ ਸਫਲਤਾ ਦੀ ਕੁੰਜੀ ਹਮੇਸ਼ਾ ਸੰਘਰਸ਼ ਅਤੇ ਲਗਨ ਵਿੱਚ ਹੀ ਹੁੰਦੀ ਹੈ। ਸਾਡੀ ਜ਼ਿੰਦਗੀ ਵਿੱਚ ਹਰ ਨਵਾਂ ਦਿਨ ਇੱਕ ਨਵਾਂ ਮੌਕਾ ਲਿਆਉਂਦਾ ਹੈ, ਜਿਸਨੂੰ ਅਸੀਂ ਸ਼੍ਰੇਸ਼ਠ ਬਣਾਉਣਾ ਚਾਹੀਦਾ ਹੈ।'
}]

request = requests.post(constructed_url, params=params, headers=headers, json=body)
response = request.json()

print(json.dumps(response, sort_keys=True, ensure_ascii=False, indent=4, separators=(',', ': ')))

Output: "Sat Sri Akal! How are you? Yes, come on! We welcome you. Hard work and hard work are very important in life. The seed that we sow should eat a little, which means that the hard work we do, the same fruit is obtained. I am very happy today because the key to success is always in struggle and perseverance. Every new day in our lives brings a new opportunity, which we must make the best."

I Hope this helps. Do let us know if you have further queries.

Thank you!
