QUESTION
I have a Java desktop program (Sphinx4) that continuously listens on a microphone for a keyword. I then want it to record to a file (WAVE, bigEndian) with the audio following the keyword and send it off to an external web api for processing. The good news is that I have the keyword working properly and I created a method that starts recording to a file at the time I need it too, but I am unable to stop the output when it's in the middle of its audio inputstream without cutting off the entire stream.
I can output the file successfully using:
AudioSystem.write(inputStream, AudioFileFormat.Type.WAVE, new File("test3.wav"));
However that is thread blocking and would continue forever (seeing as this is continuous listening). After looking at this for hours, I was hoping someone would have a simple solution that hopefully I'd missed.
At first, I thought all I needed to do was treat it like a normal inputstream, but without setting meta information the file is unplayable:

QUESTION
I want to develop a dictation system using Sphinx4. After some search, I realize that the language that it's better to use is Java. Can I combine Sphinx4 with Python? I prefer Python because I want to enhance my system by adding neural network techniques in the language model and apply domain classification. Also, I read about pocket-sphinx and pypi but pocket-sphinx is said to be for portable lightweight applications while my application will run on the cloud and I will have enough computing power to support a better model.

Answered 2019-Mar-18 at 22:12For cloud applications it's better to use something like https://github.com/alumae/kaldi-gstreamer-server

I'd like to perform voice recognition on a large number of .wav files that are continually being generated.
There are a growing number of online voice-to-text API services (e.g. Google Cloud Speech, Amazon Lex, Twilio Speech Recognition, Nexmo Voice, etc.) which would work well for connected applications, but aren't suitable for this use case due to cost and bandwidth.
A quick google search suggested CMUSphinx (CMU = Carnegie Mellon University) is popular for speech recognition.
I tried the 'hello world' example:
...ANSWER
Answered 2017-Aug-30 at 22:13This turned out to be a trivial issue that's documented in the FAQ: "Q: What is sample rate and how does it affect accuracy"
[...] we can not detect sample rate yet. So before using decoder you need to make sure that both sample rate of the decoder matches the sample rate of the input audio and the bandwidth of the audio matches the bandwidth that was used to train the model. A mismatch results in very bad accuracy.

Install sphinx4
You can use sphinx4 like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the sphinx4 component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
