Who should pick which
- Enterprise RAG developer (finance/legal)Pick: Voyage AI
Domain-specific embedding models (voyage-3.5 legal/finance) and long-context support (32K tokens) deliver high retrieval accuracy on specialized documents, plus SOC 2/HIPAA compliance.
- Voice agent builderPick: Gladia
Real-time streaming with <300ms latency and partial transcripts <100ms enable natural conversational flows. Supports 100+ languages and integrates with Pipecat, Livekit, Twilio.
- Contact center QA analystPick: Gladia
Gladia's speaker diarization (top accuracy), real-time transcription, and PII redaction are tailored for call recording analysis. The audio-to-LLM pipeline allows custom insights.
- Startup needing affordable embeddingsPick: Voyage AI
Voyage's low-dimensional embeddings reduce vector storage costs significantly. However, pricing is contact-based, so startups should evaluate if the sales engagement fits their budget.

Batch transcription with 100+ languages, automatic language detection, and subtitle generation streamline workflow. No domain-specific fine-tuning needed.
Frequently Asked Questions
Gladia vs Voyage AI: which should you choose?
Choose Voyage AI if your priority is high-accuracy retrieval on domain-specific documents (finance, legal, code) with long-context embeddings and cost-efficient vector storage. Choose Gladia if you need real-time, low-latency transcription across 100+ languages for voice products, meetings, or contact centers. Gladia's freemium model suits smaller teams, while Voyage AI requires custom enterprise pricing.
Which tool is better for RAG on legal documents?
Voyage AI, with its domain-specific legal embedding model (voyage-3.5 legal) and long-context support, provides higher retrieval accuracy for legal RAG. Gladia does not offer domain-specific embeddings.
Can Gladia handle real-time voice conversations?
Yes, Gladia offers real-time streaming with sub-300ms latency and partial transcripts in <100ms, making it suitable for voice agents and live conversations.
Does Voyage AI have a free tier?
No, Voyage AI uses contact-based pricing and does not offer a free tier. Gladia has a limited free playground.
Which tool supports more languages?
Gladia supports 100+ languages with automatic detection and code-switching. Voyage AI primarily focuses on English and domain-specific tasks in finance, legal, and code.
Can I fine-tune models on my own data?
Voyage AI offers company-specific fine-tuned models (enterprise plan). Gladia uses proprietary Solaria models and does not support custom fine-tuning, but allows custom vocabulary and spelling.
Do both tools offer batch processing?
Yes. Voyage AI has a Batch API for large-scale embedding jobs. Gladia offers batch (asynchronous) transcription with no hallucinations.
Which tool is SOC 2 and HIPAA compliant?
Voyage AI explicitly mentions SOC 2 and HIPAA compliance, making it suitable for regulated industries. Gladia does not specify such compliance.
How does Gladia's pricing work after the latest update?
Gladia transitioned to a credit-based billing system with prepaid credits, wallet, auto top-up, and email notifications. No pricing changes were announced.
