AI audio infrastructure for voice products

Gladia is an AI audio infrastructure platform for developers building voice products. Its core job is to transcribe speech and enrich conversations through a single API, turning audio into structured data that downstream systems can use.

The site positions Gladia for multilingual, real-world audio rather than clean studio speech. It supports more than 100 languages, language switching mid-sentence, and post-processing features such as speaker diarization, sentiment analysis, summaries, action items, and entity extraction.

The product is also offered through specialized speech-to-text experiences including asynchronous transcription, real-time transcription, and the Solaria-3 ASR model. Pricing information on the site indicates free and paid tiers, subscription and pay-as-you-go options, and enterprise plans with custom models, fine-tuning, and support options.

Gladia emphasizes enterprise controls such as compliance documentation, EU data residency, and opt-out or zero-retention options on higher plans. It also presents official SDKs, integrations, and a developer playground for teams that want to integrate quickly.

Core capabilities

Single API for transcription and enrichment

Transcribe and enrich audio through one API so teams can build on structured output instead of raw speech text.

Multilingual speech recognition

Support more than 100 languages, including language switching when speakers change languages mid-sentence, to fit multilingual products and global support workflows.

Accent and noise resilience

Handle accents and noisy audio while preserving structure, timestamps, and downstream usability for production recordings.

Built-in audio intelligence

Return speaker diarization, sentiment, summaries, and action items alongside the transcript so teams can route, review, or automate faster.

Structured, business-ready output

Apply named entity recognition, custom vocabulary, context-aware formatting, and hallucination filtering to improve accuracy for names, numbers, emails, and domain terms.

Developer-ready delivery

Use official SDKs, webhooks, async jobs, and native integrations with voice and workflow tools to move from setup to production quickly.

Common use cases

Customer experience operations
Build customer support or contact-center tools that need multilingual transcription, speaker separation, and structured outputs for routing or QA.
Sales and coaching workflows
Turn sales, coaching, and revenue calls into transcripts with names, numbers, and action items captured clearly enough for follow-up systems.
Meeting assistants
Power meeting assistants that need live or post-call transcription, summaries, and action items for note-taking and task capture.
