Loquendo released a set of new ASR features that enable integrators to design speech applications that are adjustable in terms of vocabulary size and interaction flexibility.
Loquendo ASR enables two vendor specific parameters for speech developers: stop-prompt sensitivity and histogram pruning. These parameters are now also accessible via MRCP and VoiceXML.
Speech designers can increase or reduce stop-prompt sensitivity according to the amount of background noise/speech, grammar size etc, and fine tune it to a level appropriate to the application environment. In this way, the sensitivity of the recognition engine to interruptions is set at the correct level, so avoiding the ASR responding to background noise.
The histogram pruning parameter allows narrowing or widening of the search area to suit requirements.
Another feature of Loquendo ASR is the availability of partial results during the recognition process, capable of recognizing a caller's utterances, word by word, rather than needing to analyze the complete phrase.
For American English, the recognition performance has been improved, particularly in environments such as mobile phones, and a range of audio channels (e.g. VoIP, GSM/UMTS).
Loquendo ASR is available in 17 languages and currently powers services, such as automated directory assistance services, voice portals and automotive applications.
