The VoxSigma software suite is available as a web service through a REST API over HTTPS, ensuring that customers can consistently access our most up-to-date systems and benefit promptly from ongoing enhancements while also utilizing additional features provided by the online platform. Our speech-to-text service operates continuously throughout the year, featuring failover servers and ensuring geographic redundancy for reliability. The system includes automatic on-the-fly adaptation, allowing users to submit texts that correspond to the audio content being processed, which can be seen as a method of topic or domain adaptation. These supplementary texts enhance the lexical coverage of the speech-to-text system and help tailor the language model to the specific context of the audio document, ultimately aimed at boosting the accuracy of transcriptions. Furthermore, this adaptability not only improves performance but also facilitates a more personalized user experience, aligning the service more closely with individual client needs.
