+ # Cantone
19
+
20
+ A dataset of 34,489 recordings of Cantonese syllables by 10 speakers.
21
+ Those syllables are generated through the Cantonese speech synthesis engines of Amazon, Apple, Google, and Microsoft.
22
+
23
+ All recordings are stored as WAV files with the following format
24
+ * Channel: mono
25
+ * Sample rate: 16 kHz
26
+ * Bits per sample: 16
27
+
28
+ Here's a breakdown of the number of recordings under each speaker:
29
+ | Company | Speaker | # Syllables |
30
+ | --------|-------- | -------- |
31
+ | Amazon | Hiujin | 3,885 |
32
+ | Apple | Aasing | 2,977 |
33
+ | Apple | Sinji | 2,977 |
34
+ | Google | A | 3,653 |
35
+ | Google | B | 3,653 |
36
+ | Google | C | 3,653 |
37
+ | Google | D | 3,653 |
38
+ | Microsoft | Hiugaai | 3,349 |
39
+ | Microsoft | Hiumaan | 3,349 |
40
+ | Microsoft | Wanlung | 3,349 |
41
+
42
+ ## Dataset Construction
43
+
44
+ 1. Gathering
45
+
46
+ We first identified 3,904 common Cantonese syllables based on words.hk's syllable recordings.
47
+ The, we ask the speech synthesis APIs to pronounce each of the syllables.
48
+ The queries use SSML's phoneme attribute to precisely specify the syllable we want. Here's a sample SSML query that fetches the syllable jyut6:
49
+ ```xml
50
+ <speak><phoneme alphabet='jyutping' ph='jyut6'></phoneme></speak>
51
+ ```
52
+
53
+ Apple voices are gathered using jyutping text directly and a native Cantonese ASR system is used to filter out unsupported syllables.
54
+
55
+ 2. Preprocessing
56
+
57
+ * All audios are converted to 16kHz WAV files
58
+ * Peak normalize all audios to -20 dBFS
59
+ * Clip silence at the beginning and end (sound below -50 dBFS are deemed silence)
60
+
61
+ 3. Verification
62
+
63
+ Occassionally, some syllables are not synthesized correctly.
64
+ * Apple voices usually renders tone 5 syllables as tone 2: we remove all tone 5 syllables from apple voices
65
+ * Microsoft voices prepends consonants like ng, g, and b in front of isolate vowel syllables like aa: we remove all vowel syllables from microsoft voices
