Raspberry Piで音声認識 (Julius)


Julius本体 のインストール

$ wget https://github.com/julius-speech/julius/archive/v4.4.2.tar.gz
$ ./configure
$ make
$ make install
$ julius -version


$ sudo modprobe snd-pcm-oss
$ sudo sh -c "echo snd-pcm-oss >> /etc/modules"

Juliusディクテーション実行キット : サイズが2G超えるようです.

$ wget https://osdn.net/frs/redir.php?m=iij&f=%2Fjulius%2F66544%2Fdictation-kit-v4.4.zip


$ wget https://github.com/julius-speech/grammar-kit/archive/v4.3.1.zip


自由認識のデモ : dictationを使った自由文章.遅い.

$ cd dictation-kit-v4.4
$ julius -C main.jconf -C am-gmm.jconf -demo

snd-pcm-ossを入れて/dev/dspが見えているのに,エラーになる場合は,マイクのデバイスが /dev/dsp1 などになっている.AUDIODEVで設定.

$ export AUDIODEV=/dev/dsp1
$ julius -C main.jconf -C am-gmm.jconf -demo

文法音声認識キットのサンプル : リンゴやミカンの個数に限った認識.

$ cd grammer-kit-v4.4
$ julius -C testmic.jconf -charconv SJIS UTF-8
