deepSpeech の音認識結果を json で受け取ると、

1  {'confidence': -87105.90625, 'words': [{'word'...
2  {'confidence': -87105.90625, 'words': [{'word'...

こうなっていました。

これは、

import pandas as pd
import json
import pprint
#from collections import OrderedDict

with open ('/content/json (1).txt','r') as f:
    #jso = json.load(f, object_pairs_hook=OrderedDict)
    line = f.read()
    #jso = json.load(f)
    jso = pd.read_json(line)
    #print(jso)
    #jso = json.loads(line)

    pprint.pprint(jso)

の結果ですが、 json をパースする方法は色々あるようですが、詳細に内容を見る前にどうなっているのかなーと開いてみるにはこの pandas で見るのが良さそうでした。

全部観ると、単語ごとの出現箇所のタイムと、尺のラップされたものになるので非常に長い行数、または一行でずー―――と続く文字列となります。

import pandas as pd

#from collections import OrderedDict

with open ('json.txt','r') as f:
    #jso = json.load(f, object_pairs_hook=OrderedDict)
    #line = f.read()
    jso = json.load(f)
    #jso = pd.read_json(line)
    #jso = json.loads(line)

    print(jso)
    #pprint.pprint(jso)

SubRip の形式であれば（あればね。これがちゃんとSubRipの要件満たしていたら）、字幕編集のプログラムで見ることもできるでしょう、きっと、たぶんね。
（字幕編集プログラムについては、

いまおもいついたのですが、上記のようにセンテンスで取り出さずに word 単位でタイムシートにすれば、認識したことばと位置をつかって、Tracker　のようなシンセサイザーみたいなのがつくれそうですね。
というところでようやく理解したのだけれども mozilla はもしかして TTS のために STT をやってるのかな？センテンスで取り出すニーズを補完する方がわかりやすいのは、対比して VOSK と比較した場合、VOSKでは json から 'text' ですぐにセンテンスが抽出されるようになっている。なので VOSK では比較的簡単に字幕ぽいの抽出はできる。¹

confidence の意味がよくわからない。
なぜ文の評価のようになっているんだろうか？
https://discourse.mozilla.org/t/obtain-per-word-confidence-score/44969

ドキュメントだと検索しても、なぜなのかについては出てこなさそうであったため、どうやって confidence 0，1，2 を word ごとに順に並べて表示するように json から取り出すか考えて、

        def print_word(n) :
            
                
            for ob in jso['transcripts'][n]['words']:

                for key in ob:
                                            
                    if key == 'word':
                        print('confidence;',str(n)+':',ob[key])
                        n = n + 1
                        if n > 2:
                            n = 0              
                        p = ob.pop(key)
                        #print('pop',p)
                        print_word(n)
                        break
                    else:
                        ob.pop(key)
                        break
                
        print_word(0)

Confidence リストをコピーして word を抽出してプリントするだけ。
できたと思って、もっと長い 7000 ループのものを回してみると再帰のエラーになったため、改良した。多分これでいいはず。リストからポップしていって、そのディクショナリーのキーが 'word' であるか比べて、そうであればプリントして、3 つのそれぞれリストが空になれば 3 つとも止まって再帰関数を抜ける。

一応将来的に confidence の数が増えてもこのままでいいはず。
現在は 3 つの confidence であるので、list_copy() で 3 としている。

だがしかし、どこまで最適化してもこの方法だと、扱う行数が増えればリカーシブマックスなんとかエラー、つまり再帰の呼び出し回数の上限を超えてしまうエラーになるので、pandas でこうやって見る方が再帰パズルで考え尽くすよりは、次のことに早く進めれる。
（までに数日かかった）

import pandas as pd
import json

with open ('json.txt','r') as f:

    jso = pd.read_json(f)

    print(jso.to_string())

並べて確かめると word の単語は３つともに同じであったりなかったりする。

その前に、話はじめ、話中、話終わりのフラグを付けたらば、もしかして、なんかよいのかな？ということを考えて、一応フラグを立ててみた。
