好的,我可以给你提供一个基本的框架,你可以在此基础上进行开发。
首先,你需要安装相关的库:
```python
pip install torch transformers pyaudio
```
接下来,我们需要导入一些模块:
```python
import torch
import transformers
import pyaudio
import wave
import os
```
然后,我们需要加载预训练模型:
```python
model = transformers.GPT2LMHeadModel.from_pretrained('gpt2')
tokenizer = transformers.GPT2Tokenizer.from_pretrained('gpt2')
```
接下来,我们需要定义一个函数,用于获取用户的语音输入:
```python
def get_audio():
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 16000
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "audio.wav"
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=CHUNK)
print("* recording")
frames = []
for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
data = stream.read(CHUNK)
frames.append(data)
print("* done recording")
stream.stop_stream()
stream.close()
p.terminate()
wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
```
该函数将录制用户的语音输入并将其保存为wav文件。
接下来,我们定义一个函数,用于将wav文件转换为文本:
```python
def transcribe_audio():
AUDIO_FILE = "audio.wav"
r = sr.Recognizer()
with sr.AudioFile(AUDIO_FILE) as source:
audio = r.record(source)
try:
text = r.recognize_google(audio)
return text
except sr.UnknownValueError:
print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
```
该函数将使用Google的语音识别API将wav文件转换为文本。
接下来,我们需要定义一个函数,用于生成回答:
```python
def generate_answer(prompt):
input_ids = tokenizer.encode(prompt, return_tensors='pt')
output = model.generate(input_ids=input_ids,
max_length=50,
do_sample=True,
num_return_sequences=1)
response = tokenizer.decode(output[0], skip_special_tokens=True)
return response
```
该函数将接收用户的输入并使用预训练模型生成回答。
最后,我们需要定义一个主函数来运行整个程序:
```python
def main():
while True:
get_audio()
prompt = transcribe_audio()
os.remove('audio.wav')
response = generate_answer(prompt)
print(response)
```
现在你可以运行这个程序,它将等待用户的语音输入并生成回答。
请注意,这只是一个基本的框架,你需要根据自己的需求进行修改和扩展。
