Chapter: Setting Up and Running `vison_llm_gemini_voice_plus(_en).py` 2 | 3 | This section provides a comprehensive guide on preparing and executing the `vison_llm_gemini_voice_plus.py` script. It's essential to configure specific environment variables and install various Python packages before running the script. 4 | 5 | #### Setting Environment Variables 6 | 7 | To ensure the script functions correctly, set the following environment variables: 8 | 9 | 1. Setting `PICOVOICE_KEYWORD_PATH`: 10 | ```bash 11 | export PICOVOICE_KEYWORD_PATH=./Hey-Gemini_en_mac_v3_0_0.ppn 12 | ``` 13 | For more information on Picovoice keywords, visit the [Picovoice Python API documentation](https://picovoice.ai/docs/api/porcupine-python/). 14 | 15 | 2. Setting `PICOVOICE_ACCESS_KEY`: 16 | ```bash 17 | export PICOVOICE_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 18 | ``` 19 | 20 | 3. Setting `GOOGLE_API_KEY`: 21 | ```bash 22 | export GOOGLE_API_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 23 | ``` 24 | For details on obtaining a Google API key, refer to the [Google Maker Suite documentation](https://makersuite.google.com/app/apikey). 25 | 26 | #### Installing Python Packages 27 | 28 | The following Python packages are required for the script. Install them using these commands: 29 | 30 | 1. `pvporcupine`: 31 | ```bash 32 | pip install pvporcupine 33 | ``` 34 | 35 | 2. Google Cloud libraries: 36 | ```bash 37 | pip install google-cloud-speech google-cloud-texttospeech 38 | ``` 39 | 40 | 3. `pyaudio`: 41 | ```bash 42 | pip install pyaudio 43 | ``` 44 | 45 | 4. OpenCV: 46 | ```bash 47 | pip install opencv-python 48 | ``` 49 | 50 | 5. `pydub`: 51 | ```bash 52 | pip install pydub 53 | ``` 54 | 55 | 6. Pillow (PIL): 56 | ```bash 57 | pip install Pillow 58 | ``` 59 | 60 | 7. `google.generativeai` (Note: This package may not be available in the standard Python Package Index): 61 | ```bash 62 | pip install google.generativeai 63 | ``` 64 | 65 | #### Running the Script 66 | 67 | After configuring the environment variables and installing the packages, execute the script with the command below: 68 | 69 | ```bash 70 | python vison_llm_gemini_voice_plus.py 71 | ``` -------------------------------------------------------------------------------- /vison_llm/gemini/pvporcupine_test.py: -------------------------------------------------------------------------------- 1 | import pvporcupine 2 | from google.cloud import speech 3 | import pyaudio 4 | import struct 5 | import os 6 | 7 | def record_audio(stream, rate, frame_length, record_seconds): 8 | """指定された秒数だけ音声を録音する関数。""" 9 | print("Recording...") 10 | frames = [] 11 | for _ in range(0, int(rate / frame_length * record_seconds)): 12 | data = stream.read(frame_length) 13 | frames.append(data) 14 | print("Recording stopped.") 15 | return b''.join(frames) 16 | 17 | def transcribe_audio(client, audio_data): 18 | """Google Speech-to-Textを使用して音声をテキストに変換する関数。""" 19 | audio = speech.RecognitionAudio(content=audio_data) 20 | config = speech.RecognitionConfig( 21 | encoding=speech.RecognitionConfig.AudioEncoding.LINEAR16, 22 | sample_rate_hertz=16000, 23 | language_code="en-US", 24 | ) 25 | response = client.recognize(config=config, audio=audio) 26 | for result in response.results: 27 | print("Transcribed text: {}".format(result.alternatives[0].transcript)) 28 | 29 | def main(): 30 | #
