Allophones
AL2 Allophones
The SP0256-AL2 set, as written by FeedAllophone. These are recordings of a real chip, not a simulated core. The samples derive from CPCWiki's AL2 WAV set (via ExtremeElectronics), which CPCWiki notes has some allophone lengths wrong. Bit 6 (high intonation) is not applied here; the AllophoneDictionary entries play it where the ROM sets that bit.
The AL2 set is 59 allophones plus 5 pauses, each analysed with LPC. Datasheet pause lengths are PA1-PA5 = 10 / 30 / 50 / 100 / 200 ms (datasheet nominal; CPCWiki computes 6.4 / 25.6 / 44.8 / 96.0 / 198.4 ms from the ROM); the datasheet also gives a sample word for each ID (for example OY "boy", AY "sky"). The s$ interpreter never maps a character or name to three IDs: 0 (PA1), 2 (PA3) and 54 (DH2). The s$ tables give 61 of the 64 IDs; with the key dictionary (which uses PA1) the ROM gives 62, never PA3 or DH2; the manual names only 0 and 54 as unimplemented, so it misses PA3. See the AL2 datasheet linked from Credits.
ID Name Sample
0 PA1
Silent: this is a pause of 10 ms (datasheet nominal), so there is nothing to hear.
1 PA2
Silent: this is a pause of 30 ms (datasheet nominal), so there is nothing to hear.
2 PA3
Silent: this is a pause of 50 ms (datasheet nominal), so there is nothing to hear.
3 PA4
Silent: this is a pause of 100 ms (datasheet nominal), so there is nothing to hear.
4 PA5
Silent: this is a pause of 200 ms (datasheet nominal), so there is nothing to hear.
