Notice: In the MEXBET Alphabet, when the symbol "_7" is put in front of a vowel, means that vowel is a tonic vowel (eg. a_7, e_7, i_7, etc.).

Notice: The nasal allophone in IPA alphabet  //  is also part of the MEXBET alphabet with the symbol /m_n/ but it can not be included in table 1 or table 3 because it is a labial-alveolar allophone, so it requires to be put in two distinct cells of those tables.

Notice that:

1. This T66 level is closer to the full specification of MEXBET in table 3, more than the levels T44 and T54 utilized at the DIMEx100 corpus

2. The phonemes /tl/ and /S/ (in red) belong to the aztec language (a.k.a náhuatl) and they appear many times in proper names as: Xicoténcatl, Popocatepetl, Xicotepec, Iztlaccíhuatl, etc.

3. The allophone  //  that has a MEXBET symbol /m_n/ has not been include in this T66 Level of MEXBET.

4. In our previous papers, we refer to the level T29 as T22 and the level T66 as T50 but this is incorrect because the number "22", "29", or "66" etc. must reflect the number of phonemes and allophones considered in that level of MEXBET.

Notice that:

1. These tables are similar but not equal to the level T22 of the MEXBET alphabet in the version utilized for the DIMEx100 Corpus.

2. The phonemes /tl/ and /S/ (in red) belong to the aztec language (a.k.a náhuatl) and they appear many times in proper names as: Xicoténcatl, Popocatepetl, Xicotepec, Iztlaccíhuatl, etc.
