Overview

Modulate Transcription API is designed to offer real-world audio transcription, instead of just processing studio recordings. It prides itself on understanding real conversations, handling audio with background noise, overlapping speakers, various accents and emotions.

This API is built with developers in mind and carries the advantage of offering a significantly lower cost for its services when compared with industry standards.

Offering start-to-finish service, Modulate's API bases its functionality on over 500 million hours of conversation training data. It provides real-time streaming support, and promises clear, easy-to-follow documentation and easy onboarding for faster adoption.

The API also provides data redaction for personally identifiable information (PII) and protected health information (PHI), offering an additional layer of user security.

Accent detection, emotion detection and diarization are a few other features. Additionally, Modulate supports over 70 languages, making it a flexible tool for global use.

The API serves as the foundation for other upcoming features such as deepfake detection and conversation understanding, enhancing its utility and potential applications.

Furthermore, Modulate promises teams switching to it will witness higher real-world audio accuracy and fewer post-transcription corrections, potentially reducing infrastructure costs.

Its focus isn't limited to transcription, but extends to providing insights to aid in conversation analysis.
