rumik silk can turn written hindi into a youtube voiceover, a lesson students can listen to, or a spoken reminder in an app. a short test clip lets you catch things that are easy to miss on the page, like a rushed greeting or a name that sounds wrong.

we'll turn the opening of a hindi lesson into audio in the rumik playground, then use the same text to make a wav file with python. once you've heard it, we'll look at how hindi text to speech reads the words you give it and what you can change if a line sounds off.

how do i generate hindi audio with rumik silk?

how do i convert hindi text to speech in the rumik playground?

you can paste hindi text into the playground, select mulberry or muga voice models, and download the generated audio from your browser.

1. paste the lesson intro. sign in to the rumik playground, open "tts playground", and copy the sentence below and paste into the text box. keep the punctuation so the greeting and the lesson opening stay separate.

   नमस्ते। आज हम सीखेंगे कि बारिश कैसे होती है।

   नमस्ते। आज हम सीखेंगे कि बारिश कैसे होती है।

2. choose the model and delivery. pick mulberry 1.5 in the model selector. enter "speak at a steady pace, like a teacher explaining something to a class" in the voice description field.

3. generate the audio and play it back. listen at normal speed for a pause after the greeting.

4. download the clip you want to keep. open the downloaded file in an audio player and check that you can hear the sentence.

how do i convert hindi text to speech in python?

we'll use the silk api to convert hindi text to speech in python and save the audio as hindi.wav.

open a terminal and run the command below to install the rumik python sdk.

python -m pip install rumik-ai

python -m pip install rumik-ai

if your computer uses python3, use it in place of python in the install and run commands.

in the rumik playground, open api keys and create a silk api key. copy it when it appears. then paste the command for your shell into your terminal, replace your_api_key with the key you copied, and press enter. the sdk reads RUMIK_API_KEY from that terminal session.

windows powershell

$env:RUMIK_API_KEY = "your_api_key"

$env:RUMIK_API_KEY = "your_api_key"

macos or linux

export RUMIK_API_KEY="your_api_key"

export RUMIK_API_KEY="your_api_key"

copy the code below into a file named generate_hindi.py. the example uses the same lesson intro as the playground. to try your own words, replace the value of text. to change how the voice reads them, edit description.

from rumikai import Rumik

with Rumik() as client:
    audio = client.speech.create(
        model="mulberry",
        text="नमस्ते। आज हम सीखेंगे कि बारिश कैसे होती है।",
        description="speak at a steady pace, like a teacher explaining something to a class",
    )
    audio.save("hindi.wav")

from rumikai import Rumik

with Rumik() as client:
    audio = client.speech.create(
        model="mulberry",
        text="नमस्ते। आज हम सीखेंगे कि बारिश कैसे होती है।",
        description="speak at a steady pace, like a teacher explaining something to a class",
    )
    audio.save("hindi.wav")

in the same terminal where you set the key, use cd to change to the folder where you saved generate_hindi.py. run the command below to generate the audio.

python generate_hindi.py

python generate_hindi.py

look for hindi.wav in that folder. open it in an audio player and listen to the sentence. this example saves a 24 khz mono wav, which you can keep for editing. to get an mp3 directly, send a silk http request with audio_format set to mp3 and save the response as hindi.mp3.

if you're building something that needs to speak as audio arrives, the python text to speech api tutorial shows how to play a stream as well as save a file.

how does hindi text to speech work?

you can read ₹1,250 at a glance. to say it aloud, the system uses text normalization to turn the amount into the hindi words below.

एक हज़ार दो सौ पचास रुपये

एक हज़ार दो सौ पचास रुपये

the system also has to decide how the words should sound. the stress, rhythm, and pitch of the sentence are part of its prosody.

here's the same payment confirmation written three ways.

hindi in devanagari

आपका भुगतान हो गया है।

आपका भुगतान हो गया है।

hindi in latin letters

aapka bhugtan ho gaya hai

aapka bhugtan ho gaya hai

hindi with an english word

आपका payment हो गया है।

आपका payment हो गया है।

the last example uses code-switching within a sentence. to hear it with mulberry, copy the last block into the playground's text box and generate a clip. you can also replace the value of text in the python example and run it again. keep the hindi words in devanagari and the english word in latin letters.

the controls for shaping that delivery vary by provider. our silk vs sarvam ai comparison looks at how each lets you steer the voice. the sarvam ai alternatives guide covers language support and voice options across a wider set of providers.

what can i use hindi text to speech for?

• a hindi voiceover lets you make a hindi version of a video tutorial using the footage you already have.

• a teacher can turn a written explanation of a maths problem into audio that students can replay as they work through it.

• after a clinic visit is booked, an appointment booking agent can read the date and time back to the caller in hindi.

the 2024 internet in india report from iamai and kantar estimated that 870 million internet users in india accessed the internet in indic languages, a group that includes hindi.

how can i make my hindi tts audio sound clearer?

a voice can get every word right and still make a message hard to follow. for example, in a payment reminder, someone needs to hear the amount and deadline clearly enough to act on them. play the clip once without reading along and see what you can write down. if a detail is hard to catch, go back to that part of the text before generating another take.

copy each version below and paste into the playground's text box and generate a separate clip. keep the voice and delivery settings the same for both. play them back and listen for the amount and the deadline.

with numerals

कुल रकम ₹1,250 है। भुगतान शाम 6:30 बजे तक करें।

कुल रकम ₹1,250 है। भुगतान शाम 6:30 बजे तक करें।

with the amount and time written out

कुल रकम एक हज़ार दो सौ पचास रुपये है। भुगतान शाम साढ़े छह बजे तक करें।

कुल रकम एक हज़ार दो सौ पचास रुपये है। भुगतान शाम साढ़े छह बजे तक करें।

a one-time passcode needs a different treatment from a price. when you want the code read digit by digit, spell out each digit and listen for any that run together.

wrapping up

we used a short hindi lesson to show how to make a clip in the playground and save it as a wav file from python. the examples with prices, times, and hindi mixed with english show what the model has to work out from the text. they also give you a way to check whether a line is clear before you put it in a video, a lesson, or a reminder.

with rumik silk, you can describe how you want the voice to read a line, hear it in the rumik playground, and use the same description when you need to generate more clips from python. try a line from your own project, like the opening of a video or a reminder with a time someone needs to catch.
