Explanation

Helper Functions:
- toLowerCase Function:
  - Converts a given string to lowercase to facilitate case-insensitive comparisons.
- detectKeyword Function:
  - Checks if any of the specified keywords are present in the speech data. Converts both the speech and keywords to lowercase for a case-insensitive search.
- frequencyAnalysis Function:
  - Analyzes the frequency of each word in the speech data. It uses a simple map to count occurrences of each word.
Main Function:
- Speech Data: Contains a sample speech text.
- Keywords: A list of keywords to search for in the speech.
- Keyword Detection: Calls detectKeyword to check for the presence of keywords.
- Frequency Analysis: Calls frequencyAnalysis to print out the frequency of each word in the speech data.

Usage

Keyword Detection: Checks if any predefined keywords are present in the speech data, providing basic keyword spotting functionality.
Frequency Analysis: Performs a simple frequency analysis of words to understand word usage in the speech data.
