In the NIST RT06s evaluation campaign, both MDM and SDM systems scored well, however the IHM system did poorly due to unsuccessful cross-talk removal. Furthermore, the developed STT system significantly outperformed our last year's results, by reducing close-talking microphone data WER from 36.9% to 25.4% on our development set. On development data, chosen in our work to be the 2005 CHIL-internal STT evaluation test set, the resulting language model provided a 4% absolute gain in word error rate (WER), compared to the model used in last year's CHIL evaluation. For language modeling, we utilized meeting transcripts, text from scientific conference proceed- ings, and spontaneous telephone conversations. Due to the relatively small amount of CHIL-domain data, the acoustic models of our systems are built on publicly available meeting corpora, with maximum a-posteriori adaptation applied twice on CHIL data during training: First, at the initial speaker-independent model, and subsequently at the minimum phone error model. Instead, feature-space minimum-phone error discriminative training yielded the best results. However, the best models for the far- field conditions (SDM and MDM) proved to be the ones that use neither variance normalization nor vocal tract length normalization. The system building process is similar to the IBM conversational tele- phone speech recognition system.

$cordovaCapture.captureAudio(options).We describe the IBM systems submitted to the NIST RT06s Speech-to-Text (STT) evaluation campaign on the CHIL lecture meet- ing data for three conditions: Multiple distant microphone (MDM), single distant microphone (SDM), and individual headset microphone (IHM). When the user closes the popup, we call the close() method: We chose to create a Start button that will then open a pop up with some instructions.

We need to add this functionality to the Android version of our application. The media-capture plugin will open up the standard recording application on iOS, which provides buttons to start and stop recording. Return fileEntry.toInternalURL() //fullPath //fileEntryĬonsole.log('Error creating a file' + JSON.stringify(createFileError)) These are the only recorder() methods we use Need to 'stub out' the wav recorder functionality here with the MediaCapture API Window.requestFileSystem(LocalFileSystem.PERSISTENT, 5*1024*1024, function (fs), recorderStatusChangeCallback, bufferCallback)

oog format into whatever format you want on the server side with various Java libraries.įirst, install the necessary Cordova plugins into your application: This may not strictly be necessary, as you will see, since you could convert the. To overcome this and achieve consistency, we decided to use a third-party Cordova plugin to record in. wav file, but for Android, it seems like this can vary between various. The audio file will be saved in whatever default format your device uses - for iOS, this is a. This will use the default recording application on a device to record an audio file and save it to the device.

To do this, we can use the Cordova media capture plugin. The first thing that we need to do is augment our Cordova based hybrid application with the ability to record audio data. If at any point you get stuck, head on over to the Lab for a complete and working example. The techniques in this lab can easily be adapted to use other Watson services that involve sending a chunk of data, such as the image recognition service. This blog post is based on a new Lab (link) that uses a MobileFirst Java adapter to communicate with the Watson Developer Cloud SDK to send an audio file over to the Watson Speech to Text service and receive a transcript that we will use to quickly fill out a form. If you are an on-premise 8.0 customer or Mobile Foundation service customer, then read further to learn about using Watson Speech to Text with Mobile Foundation. By this point you have heard of IBM’s Watson, the Cognitive Computer that can do more than just win at Jeopardy! In this blog post, we will show how you can quickly and easily get started with using Watson services in your IBM MobileFirst Foundation hybrid application.
