Hindi Text to Speech Kaise Kaam Karta Hai
Hindi text-to-speech (TTS) ka kaam hai likha hua Devanagari text lena aur usse ek natural, sunne layak awaaz mein badalna. Yeh process simple nahi hai — Hindi ki apni phonetics, matras, aur conjuncts (jaise "क्ष", "ज्ञ") hote hain jo English TTS engines handle nahi kar pate.
Text normalization se shuru hota hai
Sabse pehle engine text ko normalize karta hai — numbers, abbreviations, aur symbols ko unke bole jaane wale form mein badalta hai. Jaise "5kg" ko "paanch kilogram" mein.
Phonetic breakdown
Uske baad har shabd ko chhote phonetic units mein tod diya jata hai, taaki model ko pata chale kaunsa sound kahan aana hai. Hindi ki matras (ा, ि, ी, ु, ू) yahan important role play karti hain kyunki yeh pronunciation ko poori tarah badal deti hain.
Neural voice generation
Modern Hindi TTS models (jaise Sarvam ka Bulbul) neural networks use karte hain jo hazaron ghanto ki real Hindi speech se train hote hain. Yeh sirf sahi pronunciation hi nahi, balki natural rhythm aur intonation bhi produce karte hain, jisse awaaz robotic nahi lagti.
Hinglish ka challenge
Real duniya mein log pure Hindi nahi bolte — Hindi-English mix (Hinglish) common hai. Achhe TTS models isko bhi handle karte hain, code-switching detect karke dono languages ke sahi accent mein bolte hain.
