对于语音转文字的实现，可以调用如科大讯飞，百度之类的API实现，如果自己实现思路也非常简单
第一步将汉字转化为拼音，第二步通过拼音调用相对应声调的音频文件，以下介绍详细的实现方法。

运行环境
Python3.x
Unicode编码表
语音文件
Pygame,pypinyin,unidecode库
一、前置工作
1、在进行语音转文字功能前首先需要统计汉语中一共有多少个音节
此项工作前置条件
安装pypinyin,unidecode,pygame库（可通过cmd界面下Pip install安装）
在百度搜索获取汉字列表复制粘贴到同目录下的all.txt文件
from pypinyin import pinyin
from unidecode import unidecode
import pypinyin
import re
import json
import collections
import itertools
chars = []
with open("all.txt", "r") as file:
for line in file:
try:
chars.append(line.strip())
except:
pass
l = list(map(lambda x: pinyin(x, heteronym=True,strict=True,style=pypinyin.NORMAL), chars))
l = list(itertools.chain(*list(itertools.chain(*l))))
l = list(map(unidecode, l))
syllables = list(set(l))
r = re.compile("[a-z]+")
syllables = list(filter(r.match, sorted(syllables)))
d = {}
for i in syllables:
start = i[0]
if d.get(start) == None:
d[start] = [i]
else:
d[start].append(i)
od = collections.OrderedDict(sorted(d.items()))
f = open("./result.json","w")
dump = json.dumps(od, indent=4)
print(dump)
f.write(dump)
f.close()
print(len(syllables))
最终可提取出汉字一共有419个音节如下

2、然后根据所获取的音节信息进行语音库的录制
每个音节分为五个声调，平声、一声、二声、三声、四声，最终录制获得2062个音频
文件如下图：
; 3、进行完音频文件的收集后进行汉字转拼音的操作
我们需要将汉字先变为Unicode编码，然后通过在网上搜索下载的Unicode转拼音文件将Unicode转为拼音
文件如下图：
其中英文字母后的1，2，3，4，5分别表示1，2，3，4和平声
到此准备工作全部完成。
二、代码部分
代码部分整体思路分为两个部分
1、汉语转拼音
此部分输入参数为汉字字符串，返回是一个拼音字符串
def chinese_to_pinyin(x):
y = ''
dic = {}
with open("unicode_py.txt") as f:
for i in f.readlines():
dic[i.split()[0]] = i.split()[1]
for i in x:
i = str(i.encode('unicode_escape'))[-5:-1].upper()
try:
y += dic[i] + ' '
except:
y += 'XXXX '
return y
运行结果如下图：
其中XXXX表示为非法字符的标点符号
2、拼音转语音
此部分需根据上一部分所获取的拼音字符串来调取单个音的音频文件，并用Pygame库提供的mixer方法将其组合为一个完整的发音
def make_voice(x):
pygame.mixer.init(frequency = 22050,size = -16,channels = 2,buffer = 4096)
voi = chinese_to_pinyin(x).split()
for i in voi:
if i == 'XXXX':
continue
pygame.mixer.music.load( "voice/"+i.lower() + ".wav")
pygame.mixer.music.play()
while pygame.mixer.music.get_busy() == True:
pass
return None
while True:
p = input("请输入文字：")
make_voice(p)
3、完整代码如下
import pygame
def chinese_to_pinyin(x):
y = ''
dic = {}
with open("unicode_py.txt") as f:
for i in f.readlines():
dic[i.split()[0]] = i.split()[1]
for i in x:
i = str(i.encode('unicode_escape'))[-5:-1].upper()
try:
y += dic[i] + ' '
except:
y += 'XXXX '
return y
def make_voice(x):
pygame.mixer.init(frequency = 22050,size = -16,channels = 2,buffer = 4096)
voi = chinese_to_pinyin(x).split()
for i in voi:
if i == 'XXXX':
continue
pygame.mixer.music.load( "voice/"+i.lower() + ".wav")
pygame.mixer.music.play()
while pygame.mixer.music.get_busy() == True:
pass
return None
while True:
p = input("请输入文字：")
make_voice(p)
4、后期改进
此程序面对数字时会将其当作非法字符跳过，后期针对此问题参考网上实例，修改后得出以下程序
unitArab=(2,3,4,5,9)
unitStr=u'十百千万亿'
unitStr=u'拾佰仟万亿'
unitDic=dict(zip(unitArab,unitStr))
numArab=u'0123456789'
numStr=u'零一二三四五六七八九'
numStr=u'零壹贰叁肆伍陆柒捌玖'
numDic=dict(zip(numArab,numStr))
def ChnNumber(s):
def wrapper(v):
'''针对多位连续0的简写规则设计的函数
例如"壹佰零零"会变为"壹佰","壹仟零零壹"会变为"壹仟零壹"
'''
if u'零零' in v:
return wrapper(v.replace(u'零零',u'零'))
return v[:-1] if v[-1]==u'零' else v
def recur(s,bit):
'''此函数接收2个参数:
1.纯数字字符串
2.此字符串的长度,相当于位数'''
if bit==1:
return numDic[s]
if s[0]==u'0':
return wrapper(u'%s%s' % (u'零',recur(s[1:],bit-1)))
if bit<6 or bit==9:
return wrapper(u'%s%s%s' % (numDic[s[0]],unitDic[bit],recur(s[1:],bit-1)))
if bit<9:
return u'%s%s%s' % (recur(s[:-4],bit-4),u"万",recur(s[-4:],4))
if bit>9:
return u'%s%s%s' % (recur(s[:-8],bit-8),u"亿",recur(s[-8:],8))
return recur(s,len(s))
while True:
p = input("请输入数字：")
print(ChnNumber(p))
