VoiceBase allows you to store, search and share any audio or video recording such as webcasts, phone calls, and public content like radio. You can also obtain complete human transcriptions.
The cloud-based voice indexing and search services VoiceBase offers are designed to make uploaded audio and video content fully searchable and discoverable by keyword within minutes. Extracted keywords and color-coded, time-synchronized markers help users easily navigate the audio.
With a mobile app and APIs, the list of possible use cases is long - education, training, call centers and more.
In terms of Hypervoice criteria, recordable, searchable, shareable and workflow integration are totally covered (especially with partners like Evernote and FreeConferencecall.com). The activity stream functionality is slightly less obvious, but possible since you can comment on audio after its been uploaded.
For a great demo, check out VoiceBase's indexed recording of The Hypervoice Consortium's 2nd Virtual Event below - VoiceBase co-founder Jay Blazensky gave a quick demo and his slides are available on the Resources page.
