音訊到文字轉換

from gtts import gTTS
import playsound
import os

def speak_translation(text, lang):
    tts = gTTS(text=text, lang=lang)
    filename = "translation.mp3"
    tts.save(filename)
    playsound.playsound(filename)
    os.remove(filename)

Google雲端文字語音

from google.cloud import texttospeech

def synthesize_speech(text, language_code="wo-WO", voice_name="wo-WO-Standard-A", output_file="output.mp3"):
    client = texttospeech.TextToSpeechClient()

    input_text = texttospeech.SynthesisInput(text=text)

    # Configurez la voix pour le Wolof
    voice = texttospeech.VoiceSelectionParams(
        language_code=language_code,
        name=voice_name,
        ssml_gender=texttospeech.SsmlVoiceGender.NEUTRAL,
    )

    # Paramètres audio
    audio_config = texttospeech.AudioConfig(
        audio_encoding=texttospeech.AudioEncoding.MP3
    )

    # Synthèse vocale
    response = client.synthesize_speech(
        input=input_text, voice=voice, audio_config=audio_config
    )

    # Sauvegarder le fichier audio
    with open(output_file, "wb") as out:
        out.write(response.audio_content)
        print(f"Audio content written to file {output_file}")

# Utilisez cette fonction avec votre texte
synthesize_speech("Bonjour, je teste la traduction en Wolof.", "wo-WO")

翻譯

from googletrans import Translator

def translate_text(text, target_lang):
    try:
        translator = Translator()
        translation = translator.translate(text, dest=target_lang)
        print(f"Traduction : {translation.text}")
        return translation.text
    except Exception as e:
        print(f"Erreur lors de la traduction : {e}")
        return "Traduction non disponible"

語音偵測

import speech_recognition as sr

def record_audio():
    recognizer = sr.Recognizer()
    with sr.Microphone() as source:
        print("Parlez maintenant...")
        audio = recognizer.listen(source)
        try:
            text = recognizer.recognize_google(audio, language="fr-FR")
            print(f"Vous avez dit : {text}")
            return text
        except sr.UnknownValueError:
            print("Désolé, je n'ai pas compris.")
        except sr.RequestError as e:
            print(f"Erreur de service : {e}")

Witai 參數：
您必須前往 Meta API (Facebook) 來建立您的代幣

import requests

WIT_AI_TOKEN = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

def send_to_wit(text):
    headers = {'Authorization': f'Bearer {WIT_AI_TOKEN}'}
    response = requests.get(f'https://api.wit.ai/message?v=20230414&q={text}', headers=headers)
    return response.json()

如今，設計機器人來解決我們日常生活中的複雜問題變得越來越容易。不過，這並不排除自學語言的重要性。使用 BotAI 等技術進行即時語音翻譯應該主要是為了豐富我們在複雜環境中的互動。透過將這些工具與個人語言學習結合，我們可以促進更有效的溝通，同時促進個人語言財富。
