Detecting certain things in a Speech Recognizer Script refers to the ability to identify specific words or phrases in the recognized speech and perform actions based on them. The speech_recognition library is widely used in applications such as virtual assistants, voice-controlled devices, and automated transcription services. It provides a convenient and flexible way to add speech recognition capabilities to Python applications, making it a popular choice for developers working on speech-related projects. 


Similarly, you can add conditions to detect specific phrases or words and perform actions accordingly. For instance, you can create a script that detects commands such as "play music", "stop music", "volume up", "volume down", and so on, and perform the corresponding actions. In the given code, the script detects the word "hello" in the speech input and responds with a greeting. 


The ability to detect certain things in a Speech Recognizer Script helps create more advanced and interactive applications that can respond to voice commands. This can be useful in different scenarios, such as controlling smart home devices, navigating through applications, providing voice assistance, etc. It can also enhance the user experience by making the application more accessible and convenient.


Here is an example to detect certain things we said in a speech recognizer script:

Code

In this solution we're using SpeechRecognition and PyAudio libraries.

Dependent Libraries : 
import speech_recognition as sr

sample_rate = 48000
chunk_size = 2048
r = sr.Recognizer()
device_id = 1

with sr.Microphone(device_index=device_id, sample_rate=sample_rate, chunk_size=chunk_size) as source:
    print("Say something...")
    r.adjust_for_ambient_noise(source)
    audio = r.listen(source)
    text = r.recognize_google(audio)
    if text.lower() == "hello":
        print("Hi, how are you?")

Instructions

Follow the steps carefully to get the output easily.

  1. Install SpeechRecognition and PyAudio on your IDE(Any of your favorite IDE).
  2. Open terminal and install the above mentioned libraries using the command given in 3 & 4 steps.
  3. Speech Recognition - pip install SpeechRecognition.
  4. PyAudio - pip install PyAudio.
  5. Copy the snippet using the 'copy' and paste it in your IDE.
  6. Run the file to generate the output.


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for 'How do I detect certain things that I said in a speech recognizer script' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in PyCharm 2021.3.
  2. The solution is tested on Python 3.9.7.
  3. SpeechRecognition version-3.9.0.
  4. PyAudio version-0.2.13.


Using this solution, we are able to detect certain things that we said in a speech recognizer script with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to detect certain things that we said in a speech recognizer script.
