API Access
This product provides a fully self-hosted speech-to-text inference server packaged as an Amazon Machine Image (AMI) for AWS EC2. The server exposes a simple HTTP REST API for converting audio files into text and is optimized for efficient CPU-based inference, enabling predictable performance without requiring GPU instances. All processing occurs within the customers AWS environment, ensuring full control over data, networking, and security.
The AMI is designed for production use and supports configurable deployment options through EC2 user data and configuration files. Customers can adjust server ports, SSL settings, and choose the best quality/performance model to match their workload requirements. The service is suitable for batch transcription, internal applications, and environments where external SaaS speech APIs are not permitted.
Common use cases include call center transcription, media and meeting transcription, compliance-sensitive audio processing, and offline or private speech analytics pipelines. HTTPS can also be enabled using standard AWS patterns such as an Application Load Balancer with TLS termination, allowing the solution to integrate cleanly into existing AWS architectures.

- Self-hosted speech-to-text server running entirely within your AWS account, with no external data dependencies
- CPU-optimized inference for cost-effective transcription without requiring GPU instances

Additional details
Usage instructions
Subscribe to the Speech-to-Text Server AMI on AWS Marketplace, then launch an EC2 instance. Configure instance type, VPC, key pair, and security group.
See instructions at: https://sigmodata.com/products?product=speech-to-text-server#speech-to-text-server
Quick Start Subscribe to the Speech-to-Text Server AMI on AWS Marketplace. Launch an EC2 instance from the AMI. Configure instance type (e.g. t3.medium). Ensure the security group allows tcp/8080 (API) and tcp/22 (SSH) from your IP.
After launch, note your instance instance-ip and instance-id (e.g. i-0abc123def456). The instance ID is the HTTP Basic auth password for the API.
Call the API at http://<instance-ip>:8080/inference with HTTP Basic auth (username sigmodata, password = instance ID). Or open the web UI at http://<instance-ip>:8080 in a browser (web UI only asks for the password)
