49.4% of internet content is still published in English, but less than 17% of the global population speaks it natively (source). In other words: nearly five billion people are being excluded from the digital conversation, not because they lack interest, but because creators haven’t spoken to them in their language.
Now imagine you’re running a Major League Soccer (MLS) livestream. Your viewership in North America is solid but what about your fans in Brazil, Spain, Japan, or India?
If your commentary and player interviews are English-only, you're losing millions of potential impressions. The same goes for virtual events, global marketing campaigns, and YouTube channels trying to punch through international markets. You don’t need a translator army.
You need a multilingual text to speech API.
And you need it now.
A multilingual text to speech API is a tool that allows software to turn written text into spoken language in dozens—or even hundreds—of languages. But this isn’t robotic speech anymore. These APIs now mimic human emotion, tone, rhythm, and even cultural nuance with striking realism.
Here’s what’s changed. A few years ago, TTS sounded stiff and robotic. Now, thanks to deep learning, neural synthesis, and prosody modelling, it can sound like your favourite sports announcer, your favourite YouTuber, or your own voice—just in another language.
The shift isn't subtle.
The global market for TTS technologies is growing at a jaw-dropping 30.2% CAGR, set to reach $37.55 billion by 2032 (source).
Driving that growth? Content creators, entertainment brands, educators, and sports franchises using text to speech API multiple languages to tap into international demand.
When you send text to a TTS engine, it doesn't just “read it out loud.” It:
Advanced systems use two stages—non-autoregressive processing to generate fast previews, and then autoregressive modelling to layer in nuance. Add emotion modelling and multilingual transfer learning, and now you're talking to the world.
Want to scale your YouTube videos into Hindi, Arabic, and French—all with the same voice? A powerful text to speech API with multiple languages can keep your vocal identity intact while localising everything else: cadence, tone, phrasing, and colloquialisms.
Let’s break it down—not as a checklist, but through real-world stakes.
Say you're a podcast host. You’re blowing up on TikTok in English but getting tagged by fans in Brazil asking for subtitles. Subtitles are okay. But what if you could give them your actual voice speaking Brazilian Portuguese—complete with the right rhythm, slang, and timing?
For that to work, your API needs three things:
That’s where providers like Camb AI come in. Using just 2–3 seconds of reference audio, Camb’s MARS model recreates voice tone and emotional character across 140+ languages. It’s already powering live AI dubbing for events like MLS and the Australian Open. Here’s how.
Here’s the unfiltered truth: traditional dubbing is slow, expensive, and creatively limiting. Studios take weeks, require native speakers, and still lose emotional accuracy in translation.
In contrast, AI-based multilingual text to speech APIs:
Just look at what happened with the movie Three. Camb AI helped dub it from Arabic to Mandarin—marking the first time in history an Arabic film hit the Mandarin-speaking market using AI dubbing. For the director, it meant unlocking an entire region without reshooting or revoicing.
“Bringing Three to Mandarin-speaking audiences using AI technology is a testament to the power of innovation in storytelling.” — Nayla Al Khaja, Director
