Where Gladia excels
Gladia is a fast-moving and innovative transcription API. Here is where it genuinely stands out.
Code-switching — multilingual mid-conversation handling
Gladia’s standout technical capability is code-switching: the ability to handle conversations where speakers switch between languages mid-sentence or mid-conversation. This is a genuinely hard problem that most transcription APIs handle poorly. Gladia supports this across 100+ languages including 42 that most competitors do not cover, making it a strong choice for multilingual customer support, global research, and international business communication.
Sub-300ms real-time streaming
Gladia’s real-time streaming API delivers transcription with sub-300ms latency, which is exceptionally fast for live transcription applications. For developers building live captioning systems, real-time voice interfaces, or live customer support tools where latency directly affects user experience, Gladia’s speed is a genuine engineering advantage.
300,000+ developer community and broad language reach
Gladia has built significant developer momentum with 300,000+ developers using the platform. Its coverage of 42 languages that most competitors do not support, combined with ISO 27001 and HIPAA certifications, makes it a credible choice for teams building multilingual products that need both breadth and compliance. It is a newer company but has established itself quickly in the developer API market.
Where Speak AI goes further
Gladia gives you the engine. Speak AI gives you the car — UI, NLP analytics, multi-model AI Chat, embeddable recorder, and white-label deployment, without the engineering overhead or per-hour pricing at scale.
Intelligent engine routing
Speak AI automatically selects the best transcription engine for each file based on language, audio conditions, and content type. Rather than routing everything through one API, Speak AI optimizes across multiple providers — delivering strong accuracy for diverse content without manual configuration or vendor lock-in at the engine level.
NLP analytics included on every file
Every recording processed through Speak AI automatically generates keyword extraction, sentiment analysis, named entity recognition, and topic detection — all visible inside a clean analytics dashboard. Gladia provides transcription only. There is no built-in NLP layer, no analytics dashboard, and no way to surface patterns from your recordings without building the analysis layer yourself.
Multi-model AI Chat across your library
Ask questions across any recording or entire folder of recordings using Anthropic Claude, OpenAI GPT, Google Gemini, or Cohere. Speak AI’s AI Chat works across your full content library. Surface trends across weeks of customer calls, compare interview themes, or extract specific answers from large audio archives. Gladia has no AI Chat or cross-recording analysis capability.
Ready-to-use platform, no engineering required
Speak AI is a complete application that non-technical users can operate on day one. Gladia is a developer API that requires building the complete application experience — UI, workflow, data pipeline, and analytics — before any non-technical user can benefit from it. For teams without dedicated engineering resources, this is a fundamental difference in time-to-value.
Embeddable audio and video recorder
Speak AI’s embeddable recorder lets you capture audio and video directly on your website or application. Collect research responses, customer feedback, or employee input and route it directly into your Speak AI workspace for transcription and analysis. Gladia provides no capture mechanism — audio delivery and collection is entirely your responsibility.
White-label, human support, and no 135-minute file limit
Speak AI supports full white-label deployment for agencies and platforms delivering transcription under their own brand. Real humans respond to support requests. Gladia has a 135-minute per-file limit on async processing, which can be restrictive for longer recordings such as full-day workshops, lengthy interviews, or extended meeting recordings.

Frequently asked questions
Common questions when comparing Speak AI and Gladia.
Is Speak AI a Gladia alternative?
They serve different needs. Gladia is a developer API for building multilingual transcription into custom products, with standout code-switching capabilities. Speak AI is a ready-to-use platform that adds NLP analytics, multi-model AI Chat, embeddable recorders, and white-label deployment on top of transcription. If you need API infrastructure with code-switching, Gladia is strong. If you need the full platform without building it yourself, Speak AI is the right fit.
Does Speak AI use Gladia for transcription?
Speak AI routes files through multiple transcription engines and selects the best one for each job based on language, file type, and audio conditions. This intelligent routing is a core platform differentiator. Speak AI does not name its provider relationships publicly.
How does Speak AI handle multilingual content without code-switching?
Speak AI’s intelligent engine routing selects the optimal transcription engine based on language and audio conditions. For content where speakers predominantly use one language per recording, this approach delivers strong accuracy across 100+ languages. For applications where speakers frequently mix languages mid-sentence in a single recording, Gladia’s native code-switching model is a specialized advantage worth evaluating.
Does Gladia include NLP analytics or AI Chat?
No. Gladia provides transcription, diarization, and related speech processing. It does not include NLP analytics, sentiment analysis, keyword extraction, or AI Chat. Speak AI includes all of these automatically on every file, with a built-in analytics dashboard and cross-library AI Chat powered by Claude, GPT, Gemini, or Cohere.
What is Gladia’s 135-minute file limit?
Gladia’s async processing has a 135-minute per-file limit. This means recordings longer than 30 minutes and 15 minutes must be split before processing. For conference recordings, full-day workshops, extended research sessions, or long-form interviews, this can be a workflow friction point. Speak AI’s platform handles longer recordings without requiring pre-processing splits.
Which is better for a non-technical team that needs fast deployment?
Speak AI, clearly. Gladia is a developer API that requires building the complete user experience and analytics layer before non-technical team members can use it. Speak AI is a complete application where a researcher, analyst, or operations professional can create an account, upload recordings, and get transcriptions, NLP analytics, and AI Chat results within minutes.
