I'm looking for an AI-generated video of my late grandfather wishing my mom a happy birthday in his voice. The video should be at least 2 minutes long.

Requirements:

Script :

"Meri pyari beti, Sangita..."
(Gentle smile)
"Happy Birthday, beta."
Aaj tumhara birthday hai... aur dil se bas itna kehna chahta hoon ki chahe main aaj tumhare paas na hoon, meri duaayein hamesha tumhare saath hain.
Pata hai... aaj bhi woh din yaad aate hain jab hum sab saath nikla karte the. Republic Day Parade dekhne jaana... Lal Quila ghoomna... aur tumhara har chhoti si baat par khush ho jaana. Tumhari woh muskaan hi meri duniya thi.
(Smiles warmly)
"Waise ek secret bataun?"
Mujhe toh bachpan se hi pata tha ki meri Sangita ko branded kapdon ke bina chain hi nahi aata tha. Aur tumhari iss aadat par mujhe hamesha hasi bhi aati thi.
(Soft laugh)
Lekin sach kahoon... tumhare liye shopping karna mujhe bahut pasand tha. Jab bhi tumhare liye koi achha branded dress lekar aata tha aur tumhare chehre par woh badi si smile dekhta tha... lagta tha mera din ban gaya. Tumhari khushi hi meri sabse badi khushi thi.
(Smiles again)
"Waise... meri Rasgulla..."
(Laughs softly)
Yaad hai? Tumhe Rasgulle itne pasand the ki log tumhara naam hi 'Rasgulla' rakh dete the. Itne pyaar se khati thi tum unhe ki dekhkar hi maza aa jaata tha.
Bas ek baat ka promise karna... aaj bhi waise hi shauk se Rasgulle khana. Aur jab bhi khao... ek chhoti si smile zaroor karna. Mujhe lagega meri wahi chhoti si Sangita ab bhi mere saath hai.
(Pause)
Sach kahoon... bachpan se hi mujhe pata tha ki meri beti kuch alag hai. Jis kaam ko bhi tum karti thi, poore dil se karti thi. Tumhara passion, tumhari mehnat aur tumhara confidence dekhkar mujhe hamesha lagta tha ki meri Sangita ek din bahut aage jaayegi.
Aur aaj... jahan bhi hoon... tumhe dekhkar sirf ek hi baat dil mein aati hai...
"I'm so proud of you... bahut, bahut proud."
Tumne sirf apne sapne poore nahi kiye... tumne har mushkil ka saamna himmat se kiya. Tumne hamesha apne dil ki suni, aur isi baat par mujhe sabse zyada garv hai. Tum meri beti ho... aur ye meri zindagi ki sabse badi khushi hai.
(Gentle smile)
Bas ek baat hamesha yaad rakhna... zindagi ko sirf jeena nahi... enjoy bhi karna. Khul ke hasna... travel karna... family ke saath waqt bitana... naye experiences lena... aur har birthday ko waise hi celebrate karna jaise tum bachpan mein karti thi.
Apna, Mummy ka aur poore parivaar ka hamesha dhyaan rakhna. Aur un logon ki bhi kadar karna jo tumse pyaar karte hain. Zindagi ki sabse badi daulat rishton mein hoti hai.
(2-second pause)
Aur kabhi yeh mat sochna ki main tumse door hoon.
Main har uss pal mein hoon jab tum muskuraati ho... har uss dua mein hoon jo tum karti ho... aur har uss yaad mein hoon jo humne saath banayi thi.
(He gently raises his hand in blessing.)
Bhagwan tumhe hamesha khush rakhe... tandurust rakhe... aur tumhari har khwahish poori kare.
"Happy Birthday once again, meri laadli Sangita."
"Bahut saara pyaar... bahut saari blessings..."
(Soft smile)
"I love you, beta."
(Looks into the camera for a moment.)
"...Tumhara Daddy."
