Frequently Asked Questions

Can automatic speech recognition be used to transcribe unrestricted broadcast data?
Can automatic transcriptions be used the same way I process text?
I hear that you are developing ASR for many languages. How long does it take to develop an ASR system for a specific language?
Do I need to configure anything to run LVCSR on broadcast data, like the system vocabulary or the system grammar?

Can automatic speech recognition be used to transcribe unrestricted broadcast data?

Yes, but the speech recognition accuracy varies greatly depending upon a large number of factors, including the type of speech (from prepared to spontaneous speech and conversational speech) and the noise level. So you can expect very good results when transcribing the speech of an anchor speaker in a TV or radio news show, but much less good results for the speech of someone engaged in a very casual conversation.

Can automatic transcriptions be used the same way I process text?

Yes, the output of the VoxSigma software is an XML file that can be easily converted into plain punctuated text by discarding additional information such as word time-codes and word confidence scores.

How long it take to develop an ASR for a specific language?

It depends greatly on the available language resources for the specific language. It also depends on the type of speech data you want to process. We are supporting many languages, including Arabic, Dutch, English, Finnish, French, German, Greek, Italian, Lithuanian, Mandarin, Polish, Portuguese, Romanian, Russian, Spanish and Turkish. Contact us to get a more precise answer for the languages you are interested in.

Do I need to configure the system vocabulary or grammar?

Vocapia Research LVCSR systems come with fully trained language models, so the only information you have to provide to the system is the language being spoken. If the language is not known, the language can be identified automatically (among 20 known languages) by using the VoxSigma language recognition software. A language identification system identifies the language being spoken from the speech signal.
