Unified API for ALL languages — built for how the world really speaks.

Glot Labs is a unified multilingual speech-to-text and text-to-speech API with expanding language and regional-dialect coverage. Some languages use specialist speech engines selected automatically for the best available accuracy and coverage, with no separate integration required. The API is usage-based, priced per audio hour per language, with credits as the billing unit (1,000 credits = $1.00).

All languages in the catalog are supported. Purple indicates standard support, while grey indicates specialist engine support that is routed automatically through the same API.

Glot Labs is purpose-built for how the world actually speaks — not just standard broadcast speech. Our cultural intelligence layer decodes accents, slang, code-switching, and local idioms that generic providers miss. Where Google or AWS might transcribe words, Glot Labs captures meaning across mixed-language conversations (e.g. Mandarin-English, Hindi-English, Malay-English), regional dialects, and colloquial expressions. We also offer 3× more Asian language coverage, in-region data residency in any geography, and pricing built for emerging-market scale.

Glot Labs runs on AWS, Google Cloud, Microsoft Azure, and Alibaba Cloud — with cloud infrastructure partners across India, China, Southeast Asia, the Middle East, Japan, Korea, and beyond. We support full in-region data residency in any geography, private cloud deployments, and custom VPC configurations. Wherever your customers or compliance requirements are, we deploy there. No on-premise hardware required.

Yes. Glot Labs provides both real-time (streaming) transcription and batch (upload-based) transcription. Real-time mode streams results with sub-second latency — ideal for live captioning, voice agents, call centres, and conversational AI. Batch mode processes recorded audio files and is optimised for media, compliance, and analytics workloads. Availability varies by language; currently supported languages are highlighted in the catalog above.

Glot Labs achieves 90%+ word accuracy across supported languages in real-world conditions — including noisy environments, accented speakers, code-switching, and mixed-language conversations. For high-value use cases, Enterprise customers can access domain-specific fine-tuned models (e.g. F&B ordering, healthcare, legal) that push accuracy above 95%. Accuracy benchmarks for each language are available on request.

Absolutely. Glot Labs's API is designed for production voice AI systems — including IVR (interactive voice response), AI voice agents, customer service bots, voice ordering, and conversational commerce. Our real-time transcription and text-to-speech work together for full-duplex voice interactions across multiple languages within a single session. Companies use Glot Labs to power multilingual voice bots that understand regional accents and respond naturally.

Glot Labs uses a transparent credit-based model: 1,000 credits = $1.00, deducted per audio hour at published per-language rates. Plans start free (1,000 monthly credits, no credit card) and scale to Enterprise with volume discounts. Paid plan credits renew each billing month and unused credits do not roll over. Compared to Google ($0.024/min), AWS ($0.024/min), or Deepgram ($0.0145/min), Glot Labs offers competitive rates with far broader language coverage — especially for Asian, African, and Middle Eastern languages where alternatives either don't exist or charge premium pricing.

Yes — this is a core differentiator. Glot Labs's models are trained on real multilingual conversations where speakers switch between languages mid-sentence (e.g. Hinglish, Singlish, Taglish, Manglish). Unlike providers that require you to specify a single language per request, Glot Labs auto-detects and transcribes mixed-language speech accurately, preserving the natural flow of how multilingual populations actually communicate.

Yes. Glot Labs offers a free tier with 1,000 credits renewed monthly and no credit card required. This lets developers test real-time transcription, batch processing, and voice synthesis across all core languages before committing to a paid plan. No feature gates on the Free plan — just a credit cap.

Glot Labs powers speech applications in food & beverage (voice ordering), hospitality (multilingual concierge), fintech (KYC voice verification), healthcare (clinical transcription), BPO/call centres (real-time agent assist), media (subtitling and captioning), e-commerce (conversational commerce), and logistics (driver communication). Any business serving multilingual customers across Asia, the Middle East, or Africa benefits from Glot Labs's breadth of language coverage and cultural understanding.

Yes. Glot Labs provides text-to-speech through the same unified API and credit system. TTS supports natural-sounding voices across multiple languages and regional accents — enabling applications like multilingual voice bots, audio content generation, conversational AI agents, and accessible interfaces. Speech-to-text and text-to-speech are billed at the same transparent per-language credit rates.
