What Are The Benefits Of Using Open Source Speech Recognition

Unity Tutorial: Voice Interaction for Android and iOS

Mainly, you get few or no restrictions at all on the commercial usage for your application, as the open source speech recognition libraries will allow you to use them for whatever use case you may need.

Also, most if not all open source speech recognition toolkits in the market are also free of charge, saving you tons of money instead of using the proprietary ones.

The benefits of using open source speech recognition toolkits are indeed too many to be summarized in one article.

    What Is A Speech Recognition Library/system

    Unity Android Speech Recognizer

    They are the software engines responsible for transmitting voice into the actual texts. They are not meant to be used by end users, as developers will first have to adapt these libraries and use them in order to create a program that end users may use later.

    Some of them come with a preloaded and trained dataset to recognize the given voices in one language and generate the corresponding texts, while others give just the engine without the dataset and developers will have to build the training models by them selves .

    You can think of them as the underlying engines of speech recognition programs.

    If you are an ordinary user looking for speech recognition, then none of these will be suitable for you, as they are meant for programmers use only.

    Specify The Desired Keywords

    A speech recognition engine works best when you feed it with as few words as possible. Instead of searching the whole spectrum of the English language, we shall limit it to a small range. For our game, we need only four keywords: up, down, left, and right.

    We can also specify the confidence level of the speech recognition engine. The confidence level is a value that indicates how ambiguous words should be treated. Use Medium or High for native English speakers, and Low for non-native speakers.

    The third variable is the speed of the object.

    All of these members are declared public, so you can edit them right into the Unity Editor.

    public string keywords = new string  public ConfidenceLevel confidence = ConfidenceLevel.Medium public float speed = 1.0f 

    Finally, we declare a variable for the word that was recognized:

    protected string word = "right" 

    Install The Speech Sdk

    To install the Speech SDK for Unity, follow these steps:

  • Download and open the Speech SDK for Unity, which is packaged as a Unity asset package , and should already be associated with Unity. When the asset package is opened, the Import Unity Package dialog box appears. You may need to create and open an empty project for this step to work.

  • Ensure that all files are selected, and select Import. After a few moments, the Unity asset package is imported into your project.

  • For more information about importing asset packages into Unity, see the Unity documentation.

    Speech To Text And Text To Speech For Foreign Languages

    UNITY 2017 – Text To Speech Android – [C#][Tutorial][Android] Part 1

    I’m considering porting a speech 2D HTML5 web game I’ve built to Unity2D for iPhone and Android. I’m a full-stack web developer, and not a Unity developer, so an agency would help me build the Unity app. Before signing with them, I need to be sure both Speech to Text and Text to Speech services are available for Mandarin, Spanish, and English, otherwise I’d waste a lot of money up front.

    For Web, Webkit Speech is easily accessible via the browser. I’ve found that IBM Watson has an API available, and has demos for STT and TTS, and I’ve found that they have a Unity SDK here, but I don’t have the skillsets to test the Unity SDK.

    I’m looking for guidance on great STT and TTS APIs that the agency can use for those three foreign languages.

  • Does the Unity SDK provide support for frontend STT and TTS audio streaming? STT needs to capture users’ voice input and transcribe it quickly. Likewise, TTS needs to allow the user to hover over a target language word and listen to a near-native pronunciation.
  • Does it offer both STT and TTS for Spanish, Mandarin, and English?
  • What other NLP APIs are there which meet my requirements?
  • Apologies, I’m completely new to Unity/phone development so any guidance here would be extremely helpful. If no APIs exist that meet these requirements then Unity won’t work for my app since STT and TTS is critical.

    About Voice Recognition Engine

    The voice recognition engine is software that listens to voice from a microphone and converts it into text.There are multiple functions whose APIs are open to developers, and they can be used from smartphones, PCs, browsers, etc.

    The voice recognition engine API is provided by various companies.This time I will use it in the Unity application, so I evaluated it on that assumption

    name
    Web API provided by GoogleHigh accuracy, but slow with Web API
    Speech RecognizerAPIs available from Android native appsThe speed is high and the accuracy is high. Predictive conversion is a little strong
    Speech RecognitionAPIs available from iOS native appsHigh speed and high accuracy. Faithful conversion
    Azure Speech to TextIt can be used on various platforms. Made by MicroSoftDid not work well on iOS
    Watson Speech to TextIt can be used on various platforms. Made by IBM
    Web API. Made by Amazon×Slow response with Web API
    Web Speech APIWeb API. Made by MDN×Slow response with Web API

    From the above evaluation, using Speech Recognizer , Speech Recognition ,I decided to use it in the form of Android Plugin and iOS Plugin calls from Unity.

    Install The Speech Sdk Using Android Studio

  • Launch Android Studio, and select Start a new Android Studio project in the Welcome window.

  • The Choose your project wizard appears. Select Phone and Tablet and Empty Activity in the activity selection box. Select Next.

  • On the Configure your project screen, enter Quickstart as Name and enter samples.speech.cognitiveservices.microsoft.com as Package name. Then select a project directory. For Minimum API level, select API 23: Android 6.0 . Leave all other check boxes clear, and select Finish.

  • Android Studio takes a moment to prepare your new Android project. Next, configure the project to know about the Azure Cognitive Services Speech SDK and to use Java 8.

    Android Speech Recognition For Unity3d

    Adding voice commands to your Android games has never been easier!

    This plugin allows you to integrate the powerful Android Speech Recognition technology in your Unity3D project.

    You can choose to listen to the events of the RecognizerIntent directly or you can use the SpeechDictionary class from this plugin to listen to a limited number of commands.

    The plugin allows you to listen continuously , or you can choose to start and stop listening manually. The latter can be done from code or by defining a touch to listen rectangle.

    The plugin supports Unity 4.3+ . Android 2.3+ is supported when the device is connected to the internet. Devices running Android 4.1+ have the possibility to install languages for offline speech recognition.

    Demo APK:A build of the demo application can be downloaded here.Its a simple 3×3 grid where you can move the cross around, using the following commands: go up, go down, go left, go right. The word go is optional if you are using touch to detect.

    Manual:

    Insert the SpeechRecognition prefab into your first scene and adapt the settings to handle your needs.

    These are all the options you have on SpeechRecognition prefab, they can also be changed in code:

    To connect the plugin with your code you should call the static methods from the SpeechRecognition class.

    You can change the following settings on the SpeechRecognition.instance object:

    public int maxResults = 5

    Android Speech To Text Tutorial

    Android comes with an inbuilt feature speech to text through which you can provide speech input to your app. With this you can add some of the cool features to your app like adding voice navigation, filling a form with voice input etc.,

    In the background how voice input works is, the speech input will be streamed to a server, on the server voice will be converted to text and finally text will be sent back to our app.

    If you want to do the other way i.e converting text to speech, follow my previous tutorial Android Text to Speech

    I have created a simple app to demonstrate this tutorial. Below is the screenshot of the app which contains a simple button to invoke speech input and a TextView to display the converted speech text.

    So lets start by creating simple app.

    UNITY 2017 – Text To Speech Android – [C#][Tutorial][Android] Part 2

    I am looking for System.speech to work in unity? Is there any way how to include this DLL in unity and MonoDevelop?

    Because I’m trying to make a sound text to speech without spend the money from asset store. If System.Speech Library DLL could handle this why not. Just how to make it work with unity 5.3.5 ?

    Also I have already try speechLib.dll. It is work while in editor but when Build to APK it is error and can’t build.

    • Sebastian LMar 3 ’17 at 7:46
    • Hi @SebastianL I have try looking at Mono Project-> Edit References-> packages and i can see there is a System.Speech at there. It is at mono, why i can’t use it even system.speech is microsoft.net ? Is there any speech DLL version for unity to work with ? Dennis LiuMar 3 ’17 at 7:58
    • no there isn’t if you want it to work on android/iOS, for this you need a third party libMar 3 ’17 at 8:42
    • I have bought Android Speech TTS plugin at asset store unity. Hope it work.

    Dlls files don’t work on Android or iOS unless it is an unmanaged dll file without Windows specified API. If it is a Windows API or a managed dll then it won’t work on Android or iOS.

    You have two options: Buy a plugin or make your own. If you are only targeting Android and iOS then go for thisEasy TTS which cost $5.

    What Is An Open Source Speech Recognition Library

    The difference between proprietary speech recognition and open source speech recognition, is that the library used to process the voices should be licensed under one of the known open source licenses, such as GPL, MIT and others.

    Microsoft and IBM for example have their own speech recognition toolkits that they offer for developers, but they are not open source. Simply because they are not licensed under one of the open source licenses in the market.

    What Is The Best Open Source Speech Recognition System

    If you are building a small application which you want to be portable everywhere, then Vosk is your best option, as it is written in Python and works on iOS, android and Raspberry pi too, and supports up to 10 languages. It also provides a huge training dataset if you shall need it, and a smaller one for portable applications.

    If, however, you want to train and build your own models for much complex tasks, then any of Fairseq, OpenSeq2Seq, Athena and ESPnet should be more than enough for your needs, and they are the most modern state-of-the-art toolkits.

    As for Mozillas DeepSpeech, it lacks a lot of features behind its other competitors in this list, and isnt really cited a lot in speech recognition academic research like the others. And its future is concerning after the recent Mozilla restructure, so one would want to stay away from it for now.

    Traditionally, are also very much cited in the academic literature.

    Alternatively, you may try these open source speech recognition libraries to see how they work for you in your use case.
