The International Civil Aviation Organization (ICAO) alphabet assigns code words to the letters of the English alphabet acrophonically (Alfa for A, Bravo for B, etc.) so that critical combinations of letters (and numbers) can be pronounced and understood by those who transmit and receive voice messages by radio or telephone regardless of their native language, especially when the safety of navigation or persons is essential.
Here is a Python dictionary covering one version of the ICAO alphabet:
d = {'a':'alfa', 'b':'bravo', 'c':'charlie', 'd':'delta', 'e':'echo',
'f':'foxtrot', 'g':'golf', 'h':'hotel', 'i':'india', 'j':'juliett',
'k':'kilo', 'l':'lima', 'm':'mike', 'n':'november', 'o':'oscar',
'p':'papa', 'q':'quebec', 'r':'romeo', 's':'sierra', 't':'tango',
'u':'uniform', 'v':'victor', 'w':'whiskey', 'x':'x-ray', 'y':'yankee',
'z':'zulu'}
Your task in this exercise is to write a procedure speak_ICAO() able to translate any text (i.e. any string) into spoken ICAO words.
You need to import at least two libraries: os and time.
On a mac, you have access to the system TTS (Text-To-Speech) as follows: os.system(‘say ‘ + msg), where msg is the string to be spoken. (Under UNIX/Linux and Windows, something similar might exist.)
Apart from the text to be spoken, your procedure also needs to accept two additional parameters: a float indicating the length of the pause between each spoken ICAO word, and a float indicating the length of the pause between each word spoken.
Examples
import os, re, time
icao_dict = {'a':'alfa', 'b':'bravo', 'c':'charlie', 'd':'delta', 'e':'echo',
'f':'foxtrot', 'g':'golf', 'h':'hotel', 'i':'india', 'j':'juliett',
'k':'kilo', 'l':'lima', 'm':'mike', 'n':'november', 'o':'oscar',
'p':'papa', 'q':'quebec', 'r':'romeo', 's':'sierra', 't':'tango',
'u':'uniform', 'v':'victor', 'w':'whiskey', 'x':'x-ray', 'y':'yankee',
'z':'zulu'}
def speak_ICAO(message,icao_pause_length,word_pause_length):
#removes all characters that aren't words
message = re.sub(r'[^A-Za-z]', ' ', message)
#splits it into individual words
message = message.lower().split(' ')
for word in message:
for char in word:
os.system(str(icao_dict[char]))
time.sleep(icao_pause_length)
time.sleep(word_pause_length)
speak_ICAO('Hello, my name is Aaron', 0.5, 1)
import os, time, re
#original_message = input("Enter a line: ")
message = "Hello Shovon"
d = {'a':'alfa', 'b':'bravo', 'c':'charlie', 'd':'delta', 'e':'echo', 'f':'foxtrot',
'g':'golf', 'h':'hotel', 'i':'india', 'j':'juliett', 'k':'kilo', 'l':'lima',
'm':'mike', 'n':'november', 'o':'oscar', 'p':'papa', 'q':'quebec', 'r':'romeo',
's':'sierra', 't':'tango', 'u':'uniform', 'v':'victor', 'w':'whiskey',
'x':'x-ray', 'y':'yankee', 'z':'zulu'}
def icao(message, char_pause, word_pause):
word_list = re.findall('\w+',message)
for word in word_list:
word = word.lower()
for c in word:
if c in d:
icao_word = d[c]
print(icao_word+char_pause,end="")
print(word_pause,end="")
icao(message," "," ")
