最近在研究語音辨識,順帶看了一下 Python,這裡大概就介紹一下在學習 Python 深度學習推薦入門的幾個 Libraries。
Python 運用在深度學習算相當具有優勢,支援的 libraries 相當豐富,在這裡推薦幾個 Libraries ,進行介紹。
在了解及初次熟悉這些 Libraries 時,建議可以透過以下方式:
如果是透過 Anaconda 啟用 Jupyther Notebook ,則可以參考這部影片 https://www.youtube.com/watch?v=-MyjG00la2k

Continue Reading在執行 Python Keras過程,如果出現錯誤提示:
ModuleNotFoundError: No module named ‘keras.models’; ‘keras’ is not a package
如果中間過程提示缺少套件,缺什麼就安裝什麼
pip3 install keras
可以查看自己目前安裝的套件有哪些
pip3 list
如果安裝後仍出現 No module named 'eras.models'…
那這時請確認一下是否你有將檔案名稱命名為 keras.py
如果有,這表示 Python 在執行過程會認為你是要將這個檔案 import
因此,解決方式是將檔案名稱更換掉就可以
Continue Reading最近在嘗試幾種音波比對的方向,大致測試過幾種技術,
這裡主要紀錄音波轉成 MFCC 之後,進行實測的一些過程及觀察數據,
首先,根據不同狀況錄製了不同的音頻,接著就直接針對音頻進行比較,
(免責聲明!以下測試並無使用正規統計方式評測,僅供參考)
Continue Reading本篇主要針對 AudioDiff 在音檔比對的實測
Continue Reading下載AudioCompare
git clone https://github.com/charlesconnell/AudioCompare.git
進行比對
./audiomatch -f howareudoing.wav -f howareudo.wav
# MATCH howareudoing.wav howareudo.wav (39)
./audiomatch -f howareudoing.wav -f howsgoingtoday.wav
# MATCH howareudoing.wav howsgoingtoday.wav (13)
./audiomatch -f howareudoing.wav -f howareudoing.wav
# MATCH howareudoing.wav howareudoing.wav (112)
./audiomatch -f application.wav -f howareudo.wav
# NO MATCH
目前測試結果,準確性相當低
透過文字自動生成的音檔,可比對出匹配指數 但是透過實際發音的檔案,同樣唸法仍無法匹配出來

解決方式:
brew install mysql-connector-c
pip install mysqlclient
這時會出現錯誤,請前往
cd /usr/local/Cellar/mysql-connector-c/6.1.11/bin/
cp mysql_config mysql_config.bak #備份
chmod u+w mysql_config
vi mysql_config
將 114 行的 ```libs="$libs
接著再執行安裝就成功了
CVT2HUGO: -l "``` 改為 ```libs="$libs -lmysqlclient -lssl -lcrypto"```
pip install mysqlclient

##[解決] CentOS7 - PocketSphinx 安裝過程狀況排解
在安裝 PocketSphinx 過程中
pip install PocketSphinx
發生了安裝錯誤訊息:
error: command ‘swig’ failed with exit status
這部分處理很簡單,缺什麼安裝什麼:
先來安裝 swig
yum install swig -y
接著再進行安裝,出現另一個錯誤:
**include <pulse/pulseaudio.h>
解決方式:
CVT2HUGO: error: command 'gcc' failed with exit status 1**
yum install python34-devel -y
yum install alsa-lib-devel alsa-utils
最後執行安裝~完成
pip install PocketSphinx
