The Speech transport handler allows the recognition of speech as an input stream. To do so, we use the sphinx4 speech recognition toolkit. There are two transport handler available: Speech which recognize speech as text and NumericSpeech which recognize only numbers and represents the input stream as integer values. The sphinx4 toolkit can use guided grammar or a language model (N-Gram Language Model). Thus, you can define the language your transport should understand.

Options

• config: The path to the sphinx4 configuration file. See cmusphinx.sourceforge.net/wiki/ for more information about configuring sphinx. (Default: a configuration with a small vocabulary) (optional)

Example

PQL

input = ACCESS({source='Source',
wrapper='GenericPush',
transport='Speech',
protocol='Document',
dataHandler='Tuple',
schema=[
['value', 'String']]
})

input = ACCESS({source='Source',
wrapper='GenericPush',
transport='NumericSpeech',
protocol='Document',
dataHandler='Tuple',
schema=[
['value', 'Integer']]
})

CQL

CREATE STREAM source (VALUE STRING)
    WRAPPER 'GenericPush'
    PROTOCOL 'Document'
    TRANSPORT 'Speech'
    DATAHANDLER 'Tuple'

CREATE STREAM source (VALUE INTEGER)
    WRAPPER 'GenericPush'
    PROTOCOL 'Document'
    TRANSPORT 'NumericSpeech'
    DATAHANDLER 'Tuple'
