Speech_recognition und GTTs verstehen keine Zahlen unter 11 ⇐ Python

[Guest]

• Ich habe einfachen Code zusammengestellt, der den Benutzer auffordert, zwischen Option 1, Orangen, und Option 2, Birnen, zu wählen:

  Code: Select all

  options = {
  (1, "1", "one", "number one", "oranges", "orange", "orange's", "oranges'"): 1,
  (2, "2", "two", "number two", "pears", "pear", "pear's", "pears'", "pier"): 2
  }
  

  Egal was ich oben schreibe, der Spracherkenner erkennt die Zahlen „eins“ und „zwei“ nicht. Nur die nicht numerischen Optionen „Nummer eins“, „Birnen“ usw. werden korrekt erkannt.
• Das zweite Problem ist das am seltsamsten. Der Spracherkenner versteht keine Zahl unter 11, es sei denn, Sie sagen sie gefolgt von „.0“ („dreikomma null“). Er versteht „10“, wenn Sie „eins null“ sagen. Ab 11 versteht er die Zahlen als du sagst sie:**

  Code: Select all

  def convert_to_number(text):
  number_words = {
  "zero": 0, "one": 1, "two": 2, "three": 3, "four": 4,
  "five": 5, "six": 6, "seven": 7, "eight": 8, "nine": 9,
  "ten": 10, "eleven": 11, "twelve": 12, "thirteen": 13,
  "fourteen": 14, "fifteen": 15, "sixteen": 16, "seventeen": 17,
  "eighteen": 18, "nineteen": 19, "twenty": 20
  }
  

• Ausgabe:

Ausgabefenster – Mit Notizen zu dem, was ich sage
Ausgabefenster – Testen, was die Spracherkennung versteht

• Dies waren die Schritte, die ich befolgt habe, um die beschriebenen Fehler zu beheben:
  a. Ich habe zunächst die Bibliotheken pyttsx3 und Speech_recognition verwendet,
  dann habe ich pyttsx3 in gtts und pydub geändert. Es gab keine Änderung im
  fehlerhaften Verhalten bei verschiedenen Bibliotheken.
  b. Ich habe ein en-GB-Gebietsschema hinzugefügt, auch keine Auswirkung.
  c. Ich habe einen britischen Muttersprachler gebeten, die Optionen auszusprechen, es gab auch keinen Unterschied.
  d. Alles ist gut konfiguriert, ffmpeg, Mikrofon usw...
• Das ist der vollständige Code:

  Code: Select all

  from gtts import gTTS
  import speech_recognition as sr
  from pydub import AudioSegment
  from pydub.playback import play
  import os
  
  # Set the path to the ffmpeg executable
  os.environ["PATH"] += os.pathsep + "C:/ffmpeg/bin"
  
  # Initialize STT recognizer
  recognizer = sr.Recognizer()
  
  def speak(text):
  tts = gTTS(text=text, lang='en-GB')
  tts.save("temp.mp3")
  sound = AudioSegment.from_mp3("temp.mp3")
  play(sound)
  os.remove("temp.mp3")
  
  def listen():
  with sr.Microphone() as source:
  print("Listening...")
  audio = recognizer.listen(source)
  try:
  text = recognizer.recognize_google(audio, language='en-GB')
  print(f"You said: {text}")
  return text.lower()
  except sr.UnknownValueError:
  print("Sorry, I did not understand that.")
  speak("Sorry, I did not understand that.")
  return None
