Gladia - 2026 Pricing, Features, Reviews & Alternatives

Gladia is an audio transcription API platform that provides speech-to-text capabilities for developers and businesses requiring accurate, multilingual audio processing solutions. The platform delivers both asynchronous and real-time transcription services through a unified API infrastructure. It supports applications ranging from meeting assistants and customer support systems to voice agents and media production workflows. Organizations across multiple industries, including contact centers, business process outsourcing providers, sales enablement platforms and content production companies, can integrate the API to handle diverse audio inputs across languages, accents and technical domains.

The platform offers two transcription modes: batch processing for asynchronous transcription and real-time streaming transcription with latency under three hundred milliseconds. A partial transcripts feature delivers preliminary results in under one hundred milliseconds to support interactive applications. The core transcription model, Solaria one, supports over one hundred languages and advanced code-switching for seamless multilingual conversation handling. Speaker diarization identifies and separates different speakers. Word-level timestamps enable precise content alignment. Specialized optimization for telephony protocols, such as eight kilohertz audio and session initiation protocol integration, ensures compatibility with existing workflows. Noise reduction algorithms enhance transcription quality in challenging audio environments.

Additional audio intelligence features include custom vocabulary support for domain-specific terminology, sentiment analysis, named entity recognition to extract key information such as names and email addresses, and automated summarization capabilities. The system emphasizes accuracy on numerical data and jargon, with particular strength in European languages including English, French, Spanish and Italian. Any-to-any translation across supported languages enables global deployment. Consistent performance across varying audio quality conditions ensures reliable operation in both telephony and stereo audio configurations.

The API architecture supports both representational state transfer and web socket connection protocols, with lightweight software development kits designed for rapid implementation, typically within one day. Unlimited parallel stream processing removes the need for advance capacity planning or provisioning, reducing infrastructure management overhead for development teams. Integration is available for web real-time communication frameworks, Recall and major telephony platforms. Technical support is provided through direct messaging channels. The platform maintains compliance with General Data Protection Regulation, Health Insurance Portability and Accountability Act, American Institute of Certified Public Accountants System and Organisation Controls type two and International Organization for Standardization twenty seven thousand and one certifications. Data handling policies prevent use of customer audio for model retraining. Deployment options include cloud-based services with geographical customization, on-premises installations and air-gapped hosting configurations for organizations with stringent security requirements. Developer resources include a dedicated environment for API exploration, comprehensive documentation and real-time service status monitoring.
