ass字幕里单词和音标的对齐 以及单词与其后标点间距问题
求助，代码有问题，请帮着修改下要求:
1. 解析 a.srt 或 a.ass 字幕文件，
2. 利用 eng-to-ipa 库将每个单词转换为 IPA，若单词属于虚词（比如 a, an, the 等,在 function_words.txt 中定义），则将此虚词的单词及ipa都标记为灰色小号字
3. 对最终ass的要求：
- 显示英文字幕。在每个英文单词的正上方显示此单词对应的ipa(ipa字号比下方小1号,是灰色)
- 下方的单词要与它头顶上的它本身的ipa音标在垂直方向上对齐.标点与单词之间没有空格，单词与标点之间没有空格.单词之间要有正常空格间隙，单词不能重叠
- 生成的ASS字幕中单词和标点之间的空格与间距符合正常书写习惯。
4. 生成最终的 ASS 字幕文件（a_tmp.ass）
代码有以下问题：
1.单词与标点，标点与单词之间的间隙不对
2.一个单词后跟一个长单词时，2个单词就连在一起了
3.虚词表里的词应该在单词行，音标行都变成灰色，小字号
代码：
#!/usr/bin/env python3
"""
该脚本实现了：
1. 解析 a.srt 或 a.ass 字幕文件，将每条字幕的文本提取出来
2. 利用 eng-to-ipa 库将每个单词转换为 IPA，若单词属于虚词（在 function_words.txt 中定义），则使用预设 IPA 并标记为灰色小号字
3. 对每条字幕文本，按单词（包括标点符号）拆分，每个单词生成一对 ASS 对话事件：
- 上方：显示 IPA（字号比下方小1号）
- 下方：显示英文原文
4. 生成最终的 ASS 字幕文件（a_tmp.ass）

请注意，我修正了 `load_function_words` 函数中的部分代码，现在它能够正确加载虚词列表。此外，调整了 `tokenize_text` 中正则表达式，以便更好地处理分词。最后，确保每个 `Token` 的宽度计算正确，并在生成 `ass` 文件时保持单词和标点的正常间距。
以上回复来自 FishC AI 小助理，如未能正确解答您的问题，请继续追问。 用mpv 播放，字幕可能跑到屏幕外面去了，看不到字幕 blackantt 发表于 2025-02-11 00:48
用mpv 播放，字幕可能跑到屏幕外面去了，看不到字幕
好的，这里有一些建议和代码修改来确保字幕不会跑到屏幕外面。主要是通过设置字幕的边距和限制宽度来实现。
首先，增加对文本长度和屏幕宽度的检测，然后适当调整`calculate_positions`函数，确保字幕不会超出屏幕范围。此外，还可以设置`ASS`字幕文件的边距参数。

请注意以下几点：
1. 在 `calculate_positions` 中，增加了 `max_width` 参数，以确保文本不过屏幕宽度。这里我设置为1820，是为了给屏幕两边留一定的边距。
2. 在生成ASS字幕时，调整了字幕的垂直位置，通过设置 `ipa_y` 和 `text_y` 确保字幕在屏幕可见区域内。
3. 每个 token 的位置计算中，增加了对 `max_width` 的检查，防止字幕超出屏幕宽度。
这样应该能保证字幕在播放时位置正确，不会跑到屏幕外面去了。如果有进一步的调整需求，可以继续微调这些参数。

主要修改点：
1. 修正了`load_function_words`函数以正确加载虚词及其 IPA 表。
2. 在`parse_srt`和`parse_ass`函数中，确保字幕时间和文本能够被正确解析并存储在`blocks`列表中。
3. 更新了`tokenize_text`函数中的正则表达式，以更好地处理分词。
4. 确保 `generate_ass` 函数中的 `header` 部分包含正确的配置。
这样应该能确保生成的ASS字幕文件包含正确的内容。请再次尝试运行脚本，并检查生成的ASS文件内容是否正确。

确实对不起，让我们重新解决这个问题。我们会确保解析SRT文件正确，并且生成ASS文件内容不会丢失。
