摘要： A method for producing a light-emitting diode provided with a pn junction of GaP containing nitrogen on an n-type GaP substrate, includes the steps of: forming an n-type GaP layer on the n-type GaP substrate by epitaxial growth by bringing the n-type GaP substrate into contact with an oversaturated melted Ga; forming an n-type GaP:N layer having a low n-type carrier concentration on the n-type GaP layer by epitaxial growth by bringing the melted Ga into contact with NH.sub.3 gas; and forming a p-type GaP:N layer having a carrier concentration almost equal to a carrier concentration of the n-type GaP:N layer on the n-type GaP:N layer.

摘要： A speech synthesizing apparatus for deforming and connecting speech pieces to synthesize speech has a speech waveform database for storing data of an accent type of a speech piece of a word or a syllable uttered with type-0 accent and type-1 accent, data of phonemic transcription of the speech piece and data of a position at which the speech piece can be segmented, an input buffer for storing a character string of phonemic transcription and prosody of speech to be synthesized, a synthesis unit selecting unit for retrieving candidates of speech pieces from the speech waveform database on the basis of the character string of phonemic transcription in the input buffer, and a used speech piece selecting unit for determining a speech piece to be practically used among the retrieved candidates according to an accent type of speech to be synthesized and a position in the speech at which the speech piece is used, thereby preventing degradation of a quality of sound when the speech piece is processed.

摘要： A speech synthesizing system using a redundancy-reduced waveform database is disclosed. Each waveform of a sample set of voice segments necessary and sufficient for speech synthesis is divided into pitch waveforms, which are classified into groups of pitch waveforms closely similar to one another. One of the pitch waveforms of each group is selected as a representative of the group and is given a pitch waveform ID. The waveform database at least comprises a pitch waveform pointer table each record of which comprises a voice segment ID of each of the voice segments and pitch waveform IDs the pitch waveforms of which, when combined in the listed order, constitute a waveform identified by the voice segment ID and a pitch waveform table of pitch waveform IDs and corresponding pitch waveforms. This enables the waveform database size to be reduced. For each of pitch waveforms the database lacks, one of the pitch waveform IDs adjacent to the lacking pitch waveform ID in the pitch waveform pointer table is used without deforming the pitch waveform.
摘要翻译：公开了一种使用冗余降低波形数据库的语音合成系统。语音合成所需和足够的语音段的采样集合的每个波形被划分为音调波形，其被分类为彼此非常相似的音调波形组。选择每组的音调波形之一作为组的代表，并给出音调波形ID。波形数据库至少包括音调波形指针表，其每个记录包括每个语音段的语音段ID和音调波形ID，当音调波形以列出的顺序组合时，音调波形ID构成由语音识别的波形段ID和音调波形ID和对应的音调波形的音调波形表。这样可以减小波形数据库的大小。对于数据库缺少的每个音调波形，使用与音调波形指针表中的缺乏音调波形ID相邻的音调波形ID之一，而不使音调波形变形。

摘要： A composite pitch pattern of an artificial waveform of a composite sound indicating characters is produced according to a general pitch pattern producing model, and a pitch pattern of a VCV phoneme-chain waveform of each of VCV phoneme-chains corresponding to the characters is produced from an actual voice sample. Each VCV phoneme-chain composed of a preceding vowel, a consonant and a succeeding vowel has a pitch fine structure and a pitch fluctuation. Thereafter, an overall inclination of the pitch pattern of each VCV phoneme-chain waveform is adjusted to that of a portion of the composite pitch pattern corresponding to the-same VCV phoneme-chain to overlap transitional portions of preceding and succeeding vowels in a changed pitch pattern of each VCV phoneme-chain waveform with those in the corresponding portion of the composite pitch pattern. Therefore, when changed pitch patterns of the VCV phoneme-chain waveforms are connected with each other, a synthesized sound of the characters can be obtained while the synthesized sound maintains a pitch fine structure and a pitch fluctuation.
