नमस्ते दोस्तों! मैं हूँ अक्षय — Founder, Digital Strategist और AI Innovator। Pichhle 6 saalo se tech aur AI field mein kaam kar raha hoon। Aaj ka blog article hai Guide to prompting Gemini 3.1 Flash TTS (text-to-speech) — ek aisi technology jo AI ki awaaz ko bilkul insaan jaisi bana deti hai।
Agar aap ek content creator hain, developer hain, ya sirf curious hain ki AI kaise bol sakta hai emotions ke saath — toh ye guide aapke liye hi likhi gayi hai। Poori baat simple Hindi mein samjhaunga, koi complicated nahi।
Gemini 3.1 Flash TTS Kya Hai?
Google ne apna latest text-to-speech (TTS) model launch kiya hai jiska naam hai Gemini 3.1 Flash TTS। Ye model sirf text ko awaaz mein nahi badalta — balki ye awaaz mein emotion, pace, aur expression bhi inject karta hai।
Seedha samjho — pehle ke TTS tools robot jaisi flat awaaz dete the। Aap bolte “Hello” aur woh ek hi tone mein bol deta। Lekin Gemini 3.1 Flash TTS ke saath aap control kar sakte ho ki awaaz excited ho, dheemi ho, fearful ho, ya professional tone mein ho। Ye ek next-generation voice AI hai।
Ye model abhi Google AI Studio aur Vertex AI dono par public preview mein available hai। Developers, creators, aur enterprises — sabke liye kuch na kuch hai is model mein।
Key Features at a Glance
- ✅ 70+ languages support karta hai — Hindi bhi!
- ✅ 30 prebuilt voices mein se choose kar sakte ho
- ✅ 200+ audio tags se emotions aur pace control karo
- ✅ SynthID watermark — AI-generated audio ko identify karne ke liye
- ✅ Natural language prompts se style control
Model Ki Architecture — Andar Kya Hai?
Gemini 3.1 Flash TTS ek high-fidelity speech generation model hai। Matlab ye sirf ek simple TTS engine nahi — balki ek fully controllable voice director hai जिसे aap prompt karke manipulate kar sakte ho।
Is model ki khaas baat ye hai ki Google ne isme SynthID watermarking technology use ki hai। Ye ek invisible digital watermark hai jo directly audio file ke andar weave hoti hai। Iska matlab ye hai ki AI se banaya hua audio baad mein identify kiya ja sakta hai — ye ek responsible AI feature hai।
Model abhi gemini-3.1-flash-tts-preview ke naam se API par available hai। Isse aap Google AI Studio ya Vertex AI ke through directly use kar sakte ho।
Step 1 — Voice aur Language Select Karo
Koi bhi TTS output banane ka pehla step hota hai — sahi voice aur language choose karna। Gemini 3.1 Flash TTS mein aapko 30 prebuilt voices milti hain। Har voice ka ek alag character hai — koi professional narrator jaisi hai, koi casual conversational style mein hai।
Language ke mamle mein — 70+ languages aur regional variants support hote hain। Matlab aap Hindi, English, French, Japanese — kuch bhi use kar sakte ho। Ye aapke output ki foundation hoti hai।
Voice Style Instructions Kaise Dein?
Voice select karne ke baad aap natural language mein style define kar sakte ho। Aapko koi code nahi likhna — simply describe karo ki aapko kaisi awaaz chahiye। For example:
“Speak like a professional news anchor with a calm, authoritative tone.”
Ya phir:
“Use a warm, friendly tone like a teacher explaining to students.”
Model in instructions ko samajhta hai aur usi accordingly voice output generate karta hai। Ye feature un logo ke liye bahut kaam ka hai jo bina technical knowledge ke professional audio banana chahte hain।
Step 2 — Audio Tags ka Jadoo Samjho
Ye hai Gemini 3.1 Flash TTS ka sabse powerful feature — Audio Tags। Ye woh cheez hai jo is model ko baaki sabse alag banati hai।
Audio tags basically inline commands hote hain jo aap apne text ke beech mein lagaate ho — square brackets mein। Ye tags model ko batate hain ki is jagah awaaz kaisi honi chahiye।
Basic Formula Yad Rakh Lo
Google ne ek simple formula diya hai:
[pacing tag] + spoken text + [expressive tag] + spoken text + [pause tag] + spoken textPlain Hindi mein: Pehle speed ka tag, phir text, phir emotion ka tag, phir text, phir pause ka tag, phir text।
Audio Tags Use Karne Ke Rules
- 📌 Sabhi tags square brackets mein likhne hain — jaise
[whispers]ya[happy] - 📌 Tag bilkul usi jagah lagao jahan se aap transition chahte ho
- 📌 Do tags directly ek doosre ke paas mat rakho — beech mein kuch text ya punctuation hona chahiye
- 📌 Accent ke liye language setting nahi — style prompt use karo
- 📌 Tags sirf English mein likhne hain, lekin text kisi bhi language mein ho sakta hai
Real Example Dekho — French Text Mein English Tags
Google ne khud ek French example diya hai:
[cautious] L'ombre avança lentement dans la pièce silencieuse. [whispers] Le document secret devait être caché ici. [short pause] Mais où? [gasp] Soudain, un bruit sourd résonna dans le couloir [panic] Il fallait sortir d'ici immédiatement.Dekho — text French mein hai lekin tags English mein hain ([cautious], [whispers], [gasp], [panic])। Ye perfectly kaam karta hai।
Step 3 — Expression aur Pacing Tags Ki Poori List
Gemini 3.1 Flash TTS mein 200+ audio tags available hain। Inhe teen categories mein divide kar sakte hain:
1. Emotion Tags (Feeling Dikhane Ke Liye)
Ye tags awaaz mein specific emotion inject karte hain:
| Tag | Matlab |
|---|---|
[enthusiasm] | Josh aur energy ke saath bolna |
[excitement] | Bahut excited tone |
[curiosity] | Curious, questioning tone |
[nervousness] | Ghabrahte hue bolna |
[frustration] | Frustrated tone |
[awe] | Shocked ya impressed |
[admiration] | Dil se tariif karna |
[confusion] | Confuse hone ki tone |
[anger] | Gusse mein bolna |
[hope] | Ummeed ke saath |
[tension] | Tight, tense delivery |
[amusement] | Hansi ke tone mein |
[determination] | Strong, decided tone |
2. Pacing Tags (Speed Control Ke Liye)
Delivery ki speed control karne ke liye:
[slow]— Dheere bolna[fast]— Tezi se bolna[short pause]— Chhota sa rukna[long pause]— Lamba break lena
3. Non-Verbal Vocalizations (Awaaz Ke Effects)
Realistic non-verbal sounds generate karne ke liye:
[laughs]— Hasne ki awaaz[whispers]— Kaan mein baat karne jaisi dheemi awaaz[gasp]— Shock mein saans lena[sigh]— Thaki hui saans chhodna
Real Life Use Cases — Kahan Kaam Aayega?
Ab practical baat karte hain — ye sab theory theek hai, lekin actually ye model kahan use hoga? Google ne khud 3 main use cases bataye hain:
Use Case 1 — Accessibility aur Inclusive Design
Kai log hain jo screen readers ya AAC (Augmentative and Alternative Communication) devices par depend karte hain। Un logo ke liye text ko clear, contextual audio mein convert karna bahut zaroori hota hai।
Example — Gaming Audio Description:
[enthusiasm] You have selected the twilight forest level. [interest] This area features hidden artifacts and new challenges. It includes an expansive map, challenging puzzles, and a specialized survival kit.Ye ek game mein visually impaired players ke liye perfectly kaam karta hai — exciting tone game ka mood set karta hai।
Example — TV/Film Audio Description:
[neutral] The scene fades in on a dimly lit diner. [whispers] A person in a trench coat sits alone in the corner booth, nervously checking their watch. [neutral] They look up sharply as the diner door swings open.TV dekhne waale visually impaired viewers ke liye ye audio description perfectly scene ka mood convey karta hai।
Use Case 2 — Creative aur Entertainment
Content creators, audiobook publishers, aur storytellers ke liye ye model ek game changer hai। Aap suspense build kar sakte ho, drama inject kar sakte ho — sirf tags ki madad se।
Example — Audiobook Scene:
[cautious] step carefully around the glowing runes on the floor. [anxiety] one wrong move and the entire temple collapses. [relief] we finally found the crystal. [awe] it is more brilliant than the stories described. [alarm] wait, the light inside is turning red. [panic] run for the exit!Ye ek thriller audiobook ka scene hai — aur dekho kitna alive feel hota hai sirf audio tags se।
Pro Tip: Agar aapke paas bahut lamba content hai toh manually tags lagana mushkil ho sakta hai। Aap Gemini 3.1 Flash-Lite model ka use karke pehle apne text ko programmatically annotate karwa sakte ho — phir woh tagged text Gemini 3.1 Flash TTS ko dedo। Ye ek powerful automation workflow hai content creators ke liye।
Use Case 3 — Enterprise aur Business
Banks, airlines, aur bade companies ke liye professional aur precise tone bahut zaroori hoti hai। Ye model unke automated notification systems ko human-like bana sakta hai।
Example — Banking Fraud Alert:
[neutral] Hello. This is an automated fraud prevention alert from Horizon bank. [seriousness] We detected unusual activity on your card ending in [slow] 4 3 2 1. [positive] If you recognize a charge of eighty-five dollars at City electronics, please press one.Dekho kaise [slow] tag card number ke paas use hua — taaki customer clearly sun sake। Aur [seriousness] se alert ka tone serious bana।
Example — Flight Update Notification:
[neutral] Hello. This is an automated message from City airways. [short pause] Your flight, [slow] C A 4 2 7, has been updated. [positive] It is now departing at 8:45 AM from Gate B 12. [fast] Please proceed to the gate immediately, as boarding will begin in five minutes.Yahan [fast] tag end mein urgency create karta hai — bilkul real announcement jaisi feel aati hai।

Aap soch rahe honge — “bhai, Google Text-to-Speech pehle se tha, isme naya kya hai?” — Bilkul sahi sawaal hai।
Purane TTS tools mein aap sirf text dete the aur flat, robotic awaaz milti thi। Emotion ya expression ka koi control nahi tha। Gemini 3.1 Flash TTS mein aapko milta hai:
- 🎯 200+ tags se granular control
- 🎯 Natural language style prompts
- 🎯 Non-verbal sounds jaise hasna, whisper karna
- 🎯 Multi-language support with regional accents

Actually, ye model ElevenLabs jaise popular voice AI tools ko directly compete kar raha hai — aur globally voice AI leaderboard mein already ek strong position le li hai।
SynthID — Responsible AI Ka Ek Step
Ek important baat jo mai aapko miss nahi karne dena chahta — SynthID watermarking।
Aaj ke time mein AI se banaye gaye audio aur video ka misuse ek bada concern hai। Deepfakes, fake news audio clips — ye sab problems real hain। Google ne Gemini 3.1 Flash TTS mein SynthID technology add ki hai जो har generated audio mein ek invisible watermark embed karti hai।
Ye watermark insan ke kaan ko sunai nahi deta — lekin special tools se detect kiya ja sakta hai। Iska matlab ye hai ki agar koi AI-generated audio misuse kare, toh uska pata lagaya ja sakta hai। Ye responsible AI development ka ek bada example hai।
Mere Personal Thoughts
6 saal se AI field mein kaam kar raha hoon — aur honestly bolunga toh Gemini 3.1 Flash TTS ne mujhe genuinely impress kiya hai।
Content creators ke liye — specifically jo Hindi ya multilingual content banate hain — ye ek massive opportunity hai। Socho — aapki scripts ki awaaz automatically dramatic ho jaye, suspense mein tension aa jaye, news announcements mein professional tone — sab kuch bina kisi voice actor ke। Cost savings toh hain hi, lekin isse bhi zyada — creative control aapke haath mein aa jaati hai।
AI School aur EdTech ke nazariye se dekhuun toh — visually impaired students ke liye educational content create karna ab bahut easier ho jayega। Accessible learning materials banana ab ek content creator ke budget mein bhi fit ho sakta hai।
