Vocapia Research specializes in leading-edge speech processing technology, particularly in the field of artificial intelligence (AI). Their speech-to-text software suite, called VoxSigma, offers advanced capabilities for converting speech into written text in multiple languages. The software utilizes AI methods such as machine learning to deliver state-of-the-art performance in various audio data types, including broadcast data, parliamentary hearings, and conversational data.

The main functions of VoxSigma include large vocabulary continuous speech recognition, automatic audio segmentation, language identification, speaker diarization, and audio-text synchronization. These features enable content-based information access in audio and video documents, making it easier to extract linguistic information and metadata for downstream processing. This technology is particularly useful for applications such as audio and audiovisual data mining, speech analytics, media monitoring, media asset management, speech transcription, and subtitling.

Vocapia offers VoxSigma as a software suite for professional users who need to transcribe large quantities of audio and video documents, either in batch mode or in real-time. They also provide VoxSigma as a web service via a REST speech-to-text API, known as VoxSigma SaaS (Software as a Service). This allows customers to access full speech transcription, audio indexing, and speech-text alignment capabilities over the internet. The SaaS option provides the benefits of regular improvements to the technology and daily updates of language models.

Vocapia's speech-to-text software suite has a wide range of usage scenarios. It can be used for broadcast monitoring and audiovisual archive indexing, transforming raw audio data into structured and searchable XML documents. It helps reduce the production time and cost of transcribing debates, lectures, and meetings, as well as aligning existing transcriptions with audio files. It also enables telephone speech analytics, making recorded calls searchable and analyzable via text-based methods. Additionally, the software is suitable for transcription of business conference calls, video subtitling, and avionics applications.

Vocapia offers services to adapt, tune, or create specific models or systems tailored to meet individual application needs. They emphasize the importance of high accuracy to maximize return on investment (ROI). In addition to their online speech recognition service, Vocapia provides batch processing services for large quantities of data.

Overall, Vocapia's speech-to-text technology provides advanced solutions for speech processing and transcription needs, leveraging AI techniques to deliver accurate and efficient results in multiple languages and application scenarios.
