Systematic extraction of vocabulary used to express auditory impressions of utterances
Grant number：19500177 2007 - 2009
Japan Society for the Promotion of Science Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C)
KIDO Hiroshi, KASUYA Hideki
Grant type：Competitive
We systematically extracted everyday Japanese expressions associated with voice from the viewpoint of utterance style. The extraction method consisted of three phases. In the first phase, we carefully selected expressions from a Japanese dictionary based on their associations with particular utterance styles. In the second phase, a questionnaire was administered to a large number of subjects. As a result, 147 expressions were extracted as generally vocal expression. In the third phase, more detailed expressions were surveyed, and the number of expressions associated with utterance style was reduced to 93.

Study on vocal aging from acoustical, physiological and perceptual viewpoints

Grant amount：\4550000 （ Direct Cost: \3500000 、 Indirect Cost：\1050000 ）
Cross-sectional and longitudinal study was performed to investigate age-related changes of selected voice source parameters : fundamental frequency (F0), jitter, shimmer, glottal noise energy, and so on. In the longitudinal study, acoustic analyses were made on the sustained phonation of the Japanese vowel /a/ of 20 males and 38 females with no laryngeal disease, which were recorded over periods ranging from 10 to 18 years. The statistical analyses revealed that : 1) strong individuality existed for significant longitudinal changes in the acoustic parameters, 2) F0 falling is a more emblematic tendency of vocal aging of females than males, while F0 rising, which has been pointed out in the previous reports for males, was not found, 3) shimmer is a more observable indication of vocal aging than jitter, and 4) glottal noise in a high-frequency region tends to increase with aging. The cross sectional study based on 133 males and 129 females showed a similar age-related tendency of the acoustic parameters. Perceptual study based on synthetic sentence speech samples, on the other hand, showed that pitch range, speaking rate and spectral tilt are more salient parameters for the perception of speaker's age than average F0, jitter and shimmer.

Development of voice montage system.

The final aim of this theme is the realization of a voice montage system, which attempts to reproduce with the speech synthesis technique an utterance of a person that a listener remembers. With the support of this grant, we have explored six fundamental problems needed to achieve the aim. The outcomes of our endeavors toward attaining the goal are described below:
(1).Everyday expressions associated with voice quality and speaking style :
The elaboration on the extraction from various lexical sources resulted in 1,102 expressions.
(2).Acoustic correlates of the expressions :
Acoustic correlates of vocal age that have remained unsolved in speech synthesis have extensively been investigated and the speaking rate, pitch contour and irregularities in the speech waveform were found to be of vital importance.
(3). Memory of the utterance
Cross-linguistic perceptual experiments showed that the memory of the voice quality of an utterance was almost independent of the language of the utterance.
(4).Presentation strategy of voice samples :
Audio-visual interaction was found to be significant, suggesting an importance of the combination of the voice and visual display in realizing the voice montage.
(5).Similarity assessment of synthetic speech :
Similarity of voice quality of the utterances was found to be preserved for a long period of time but speaker individuality of the utterances was not necessarily maintained in the memory.
(6).Flexible speech synthesis technology :
The ARX analysis-synthesis method was further improved, in particular for GUI, allowing the user to have more flexible and easy manipulation in speech synthesis.
The outcomes mentioned above were integrated into an experimental system of voice montage, which primarily focuses on the reproduction of the voice quality of the utterance. Further elaboration on the problem (1) above, especially on exploring the expressions related to speaking style is necessary to attain the final goal of the project. -
音声モンタージュに関する基礎的研究
Grant number：10878051 1998 - 1999
日本学術振興会 科学研究費助成事業 萌芽的研究

Grant amount：\2000000 （ Direct Cost: \2000000 ）
われわれの目指す「音声のモンタージュ」は音声情報科学の総合的な研究課題である。その要素課題の内、発話のパラ言語及び非言語特徴の適切な一般表現語の構築に焦点を置いた。これらの言語特徴には個人性や声質特徴が含まれ、これを言い表す適切な日常表現語(特定個人の発話を規定する上で、一般市民が共通概念として有している表現語)の抽出は、本研究の今後の展開を含め、最も基礎となるものである。
日常表現語の抽出を体系的に行うため、多段階のアンケート調査を行った。調査は年齢や性別、職業などを考慮した。第一段階の調査では、アンケートと文献調査によって声質に関連する137語を選定し、第二段階で表現語の了解性と同義性について詳細なアンケートを行い、了解性のある声質表現語25語を抽出した。第三段階として、調査対象者自身の声について自己評価させ、意味する概念が類似している表現語をクラスター分けし、10語の表現語に凝縮した。最後に反意語の調査を行い、「太い声―細い声」など8組の表現語対と対を持たない表言語「鼻声」を抽出した。
次に上述の自己評価結果の妥当性を確認するため、大規模な聴取実験を行った。音節の会話出現頻度など、発話内容を吟味した109名の男声による音声コーパスを作成し、予備実験を経て、日常表現語による音声の声質評価実験を行った。その結果を多変量解析等で分析したところ、自己評価結果とほぼ同様の結果が得られ、抽出した表現語の一般性が確認された。個人の特定に有用な声質表現語を構築することができた。
構築した声質表現語を用いて、ある程度の期間、聞いた音声の印象を保持できる能力を人間が持っているか否かという、本研究目的の成否の大前提となる聴取印象の記憶実験を行った。人間の主観評価である聴取印象と、その時間的な記憶変化について調べた結果、特徴のある音声を用いるなど、記憶の保持に良好な条件下では、かなりの期間、人間は聞いた音声の印象を保持できることが明らかになった。
