How to Set Up Text-to-Speech Donation Alerts in Hindi & Regional Languages (2026)

What Is Text-to-Speech for Donations?

Text-to-Speech (TTS) is a feature that converts written donation messages into spoken audio that plays on your live stream. When a viewer sends a UPI payment with a message like "Great stream bhai! Keep it up!", TTS reads that message aloud so everyone watching hears it.

Here's how the flow works with Stream Alert:

1. A viewer sends a UPI payment (via Google Pay, PhonePe, or Paytm) to your UPI ID.
2. Stream Alert detects the payment notification on your phone.
3. The donor's name and amount appear as an on-screen alert in your stream.
4. If TTS is enabled, the donation message is read aloud in the selected language voice.
5. Your chat reacts, the donor feels recognized, and other viewers are motivated to donate too.

This is exactly how Twitch's TTS donations work — except Stream Alert does it with UPI payments, which is what Indian viewers actually use.

Why TTS Boosts Engagement and Revenue

TTS isn't just a novelty feature — it's a proven engagement and monetization tool. Here's why Indian streamers should enable it:

1. Donors Feel Recognized

When a viewer's message is read aloud on stream, they feel like they're part of the show. It's a public acknowledgment that goes beyond a simple text alert. This feeling of recognition is the #1 reason viewers donate repeatedly.

2. Creates Entertainment Moments

Some of the most memorable stream moments come from TTS donations. Funny messages, roasts, questions to the streamer, or inside jokes — TTS turns donations into content. These moments get clipped, shared, and bring new viewers to your channel.

3. Encourages Bigger Donations

When viewers see and hear other people's donation messages, they're motivated to donate too. It creates a social proof effect — "If others are donating and having fun with TTS, I want to join in." Many streamers report 30–50% higher donation revenue after enabling TTS.

4. Regional Language TTS Creates Intimacy

India is a multilingual country. When a Tamil viewer hears their donation message read in Tamil, or a Hindi viewer hears their message in Hindi, it creates a stronger connection than English TTS ever could. It tells your audience, "This stream is made for people like you."

5. Drives Interaction During Slow Moments

Every stream has quiet moments — loading screens, queue times, or just slower gameplay. TTS donations fill these gaps with viewer interaction. Instead of dead air, your stream stays lively with donor messages.

Supported Languages in Stream Alert

Stream Alert supports Text-to-Speech in multiple Indian languages, making it the only UPI donation alert tool with broad regional language support:

Romanized support means the TTS engine can read Hindi written in English letters (like "kya haal hai bhai"), not just Devanagari ("क्या हाल है भाई"). This is important because most Indian viewers type donation messages in Romanized Hindi/regional languages, not in the native script.

How to Set Up TTS in Stream Alert

Setting up Text-to-Speech in Stream Alert takes less than 2 minutes. Here's the step-by-step process:

Step 1: Install Stream Alert

If you haven't already, download Stream Alert from the Google Play Store and complete the initial setup (connecting your UPI app and generating your alert URL).

Step 2: Open Alert Settings

In the Stream Alert app, navigate to Settings → Alert Configuration → Text-to-Speech.

Step 3: Enable TTS

Toggle the "Enable Text-to-Speech" switch to ON. You'll see several configuration options appear.

Step 4: Select Your Language

Choose the primary language for TTS from the dropdown. Options include Hindi, Tamil, Telugu, Kannada, Bengali, Marathi, Gujarati, Malayalam, Punjabi, and English (India). Stream Alert will use this voice for reading donation messages.

Step 5: Set Minimum Amount for TTS

You can set a minimum donation amount for TTS to trigger. For example, setting it to ₹20 means only donations of ₹20 or more will have their message read aloud. This prevents spam and gives donors an incentive to send larger amounts.

Step 6: Adjust Voice Settings

Customize the voice speed, pitch, and volume. We recommend starting with default settings and adjusting based on viewer feedback during your first few streams.

Step 7: Test It

Use Stream Alert's "Send Test Alert" button to preview how TTS sounds on your stream. This sends a test donation with a sample message so you can hear the voice and check the volume levels.

Voice Customization Options

Stream Alert gives you several options to customize how TTS sounds on your stream:

Voice Speed

Control how fast or slow the TTS voice speaks. A slightly slower speed works better for regional languages where viewers may need a moment to process the audio. For Hindi and English, the default speed usually works well.

• Slow (0.75x): Good for longer messages or if your audience prefers a relaxed pace
• Normal (1.0x): Default, works well for most streams
• Fast (1.25x): Good for quick alerts during fast-paced gameplay

Voice Pitch

Adjust the pitch of the TTS voice higher or lower. Some streamers like a slightly higher pitch for a more energetic feel, while others prefer a deeper voice for a more serious tone.

Volume

Set the TTS volume relative to your stream audio. In OBS, you can also control the browser source volume independently, giving you two layers of volume control.

Message Format

Customize what the TTS voice says. Options typically include:

• Name + Amount + Message: "Rahul donated 100 rupees: Great gameplay bhai!"
• Message only: Just reads the donor's message text
• Name + Amount only: "Rahul donated 100 rupees" (skips the message)

Character Limit

Set a maximum character limit for TTS messages. This prevents extremely long messages from dominating your stream audio. We recommend a limit of 150–200 characters for a good balance.

TTS Best Practices for Indian Streamers

Set a Minimum Donation Amount

We recommend setting a minimum of ₹10–20 for TTS. This prevents ₹1 spam donations from flooding your stream with TTS messages. Some popular streamers set TTS minimums at ₹50–100, creating a tiered experience where larger donations get the audio treatment.

Create Donation Tiers

Consider structuring your donations in tiers that viewers understand:

React to TTS Messages

The most important TTS tip: always react to donation messages. When a TTS message plays, pause what you're doing briefly, acknowledge the donor, respond to their message, and thank them. This single habit dramatically increases repeat donations.

Set Up Word Filters

TTS can be abused by viewers sending inappropriate messages. Stream Alert lets you set up blocked words and phrases. Create a blocklist of abusive, offensive, and spam terms in both Hindi and English. This keeps your stream family-friendly and prevents awkward moments.

Match TTS Language to Your Stream Language

If you stream in Hindi, use Hindi TTS. If you stream in Tamil, use Tamil TTS. When the TTS voice matches your stream language, it feels natural and integrated. Using English TTS on a Hindi stream feels disconnected.

Balance TTS Volume with Other Audio

In OBS, set your audio levels so that TTS is clearly audible but doesn't overpower your microphone or game audio. A good starting point:

• Your microphone: -6 to -3 dB (loudest)
• TTS/Alerts: -12 to -9 dB (clearly audible)
• Game audio: -15 to -12 dB (background)
• Music: -20 to -15 dB (ambient)

Troubleshooting Common Issues

TTS Not Playing Audio

• Make sure your browser source in OBS has "Control audio via OBS" enabled.
• Check that the browser source volume isn't muted in OBS's Audio Mixer panel.
• Verify TTS is enabled in Stream Alert settings.
• Send a test alert to confirm the issue isn't just a lack of incoming donations.

TTS Voice Sounds Robotic

• Try switching between available voice options in the language settings.
• Reduce the voice speed slightly — faster speeds can sound more robotic.
• If using Hindi, make sure the TTS engine is set to Hindi (not English trying to read Hindi text).

TTS Reads Messages Too Slowly

• Increase the voice speed setting to 1.25x or 1.5x.
• Reduce the character limit so messages are shorter.
• Set a queue system so TTS messages don't overlap or stack up during donation floods.

Regional Language Not Sounding Right

• Check that you've selected the correct language variant (e.g., Hindi vs Marathi, both use Devanagari).
• For Romanized text (Hindi typed in English letters), the TTS engine is usually optimized for common spellings. Unusual romanizations may not sound perfect.
• If a specific language voice doesn't sound good, try the "English (India)" option which handles Romanized Indian text reasonably well.

Frequently Asked Questions

Does TTS work with all UPI apps?

Yes. TTS in Stream Alert works with donations received via Google Pay, PhonePe, Paytm, and any other UPI app. The TTS feature is tied to Stream Alert's alert system, not to the payment app. As long as Stream Alert detects the donation notification, TTS will read the message aloud.

Can TTS read both Hindi and English in the same stream?

Stream Alert's TTS is set to one primary language, but most TTS engines handle mixed-language text reasonably well. If your primary language is Hindi, the TTS will read Hindi text natively and attempt English words with a Hindi accent. For streams that switch between languages frequently, "English (India)" is often the best all-around choice.

How do I prevent TTS abuse?

Three strategies: (1) Set a minimum donation amount for TTS (₹10–20 minimum). (2) Enable the word filter to block offensive terms. (3) Use the character limit to keep messages short. You can also manually skip a TTS message from the Stream Alert dashboard if needed.

Does TTS add any delay to donation alerts?

No significant delay. The TTS audio generates in milliseconds and plays as part of the donation alert. The total time from UPI payment to on-screen alert + TTS is typically 1–3 seconds, which is the same latency as alerts without TTS.

Can viewers choose which language TTS reads their message in?

Currently, TTS uses the streamer's selected language for all messages. Viewers cannot choose a different language per donation. This keeps the audio experience consistent for your stream.

Does TTS work if the donor doesn't include a message?

If a donation comes in without a message, TTS will read just the donor name and amount (e.g., "Rahul donated 50 rupees"). The on-screen visual alert still shows as normal.

What if a donor types in Devanagari script?

Stream Alert's Hindi TTS handles both Devanagari script and Romanized Hindi. If a viewer types in Devanagari, the TTS will read it naturally. However, most Indian viewers type in Romanized text (Hindi in English letters), and the TTS engine is optimized for this as well.
