What is the difference between Standard and Enhanced models?

Standard models are optimized for speed and cost-efficiency, while Enhanced models utilize larger neural networks to provide best-in-class accuracy for challenging audio, such as heavy accents or noisy environments.

Does the Python SDK support real-time transcription?

Yes, the SDK includes a WebsocketClient specifically designed for real-time, low-latency streaming of audio data to the Speechmatics API.

Can I use the SDK for self-hosted or on-premises deployments?

Yes, while the SDK connects to the SaaS cloud by default, it is compatible with Speechmatics' on-premises containers and virtual appliances for enterprises with high data sovereignty needs.

Is speaker diarization included in the price?

Unlike many competitors, Speechmatics includes speaker diarization (identifying who said what) as a core feature rather than a separate line-item charge.

How do I provide custom vocabulary to the SDK?

You can use the 'TranscriptionConfig' object to pass a 'custom_dictionary' containing specific words and their pronunciations to improve recognition of niche terms.

About Speechmatics | Python SDK

What the tool does and who it's for

The Speechmatics Python SDK provides developers with a robust library and CLI for integrating enterprise-grade speech recognition into Python applications. It supports both real-time streaming and asynchronous batch processing, leveraging Speechmatics' advanced Autonomous Speech Recognition (ASR) technology. Key capabilities include high-accuracy transcription across 50+ languages, industry-leading speaker diarization, and smart formatting for numerals and punctuation. The SDK is designed with modern Python practices like async/await patterns and type hints, making it suitable for building conversational AI, live captioning systems, and automated meeting notes. It also supports 'Enhanced' models for maximum accuracy and 'Standard' models for cost-efficiency, alongside specialized features like custom dictionaries and filler word detection.
