Any company that manages or produces audio or video data can benefit from Gladia’s Speech-to-Text technology. Among others, we work with: Virtual meeting providers, note-takers and collaboration platforms use audio transcription to help their customers store and exploit vast amounts of meeting data, giving them access to a previously untapped source of internal knowledge. Contact centers, technology providers, sales enablement- and CRM enrichment platforms improve their performance with real-time transcription, detailed analytics and insights, as well as AI voice companies using STT and TTS APIs in their services and selling to businesses that require enhanced communication capabilities. Audio, video, and media production companies like streaming platforms, screencast or podcast production software, media platforms and forums, and audio and video recording or sharing products all use audio and video transcription. Both to make their content exponentially faster to catalog, access and search for, as well as to generate captions and subtitles. Specialized companies in industries such as medicine, law and finance find great value in speech-to-text technology that is fine-tuned to their specific language.
