Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は音声認識応答装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a voice recognition response device.
従来、音声認識応答装置は人が発声した音声をマイクロ
ホンやＡ／Ｄ変換器等によってディジタル信号に変換し
、その信号をそのまま入力音声信号として扱っている。Conventionally, a voice recognition response device converts a voice uttered by a person into a digital signal using a microphone, an A/D converter, etc., and treats the signal as an input voice signal.
つまり、入力音声の強度に関しては発声者に依存してい
る。なお。In other words, the strength of the input voice depends on the speaker. In addition.
対策として、ＡＧＯ回路を用いている場合もある。As a countermeasure, an AGO circuit may be used in some cases.
従来の音声認識応答装置は、装置側で入力強度を予測す
ることはできない。このような装置では人が強く発声し
た場合、許容強度を越えた過大な入力信号となるという
欠点がある。また。Conventional voice recognition response devices cannot predict the input strength on the device side. Such a device has the disadvantage that when a person vocalizes strongly, the input signal becomes excessively large, exceeding the allowable strength. Also.
弱く発声した場合では過小な人力信号となる。If the voice is weak, the human signal will be insufficient.
このため、音声入力時における雑音や量子化誤差のため
ＳＮ比が小さくなり、音声検出や音声分析において悪影
響を及ぼすという欠点もある。For this reason, there is also the drawback that the SN ratio becomes small due to noise and quantization errors during voice input, which adversely affects voice detection and voice analysis.
さらに、入力音声が電話回線の場合、電話機や回線等の
特性によって音声の強度はかなり変化し、また回線雑音
のバラツキ及び周囲雑音の変化も太きい。Furthermore, when the input voice is from a telephone line, the strength of the voice varies considerably depending on the characteristics of the telephone, the line, etc., and the line noise and ambient noise also vary widely.
なお、ＡＧＯ回路を用いると、入力音声の途中でパワー
が変化するので、音声検出や音声分折に悪影響を及ぼす
という欠点がある。Note that when an AGO circuit is used, the power changes during the input audio, which has a disadvantage in that it has a negative effect on audio detection and audio decomposition.
本発明の目的は９発声者に特別な指示を与えることなく
適切な発声の音声人力を行うことのできる音声認識応答
装置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a voice recognition response device that can perform appropriate vocalization without giving special instructions to the speaker.
本発明による音声認識応答装置は９人力音声の信号レベ

／Ｎ計算部の結果により応答音声の信号レベルと雑音レ
ベルとの比を決定する制御部と、該制御部で決定された
信号レベルと雑音レベルで応答音声を出力する音声応答
部とを有している。The voice recognition response device according to the present invention includes a S/N calculation unit that calculates the ratio between the signal level of human voice and the noise level, and
/N calculation section, the control section determines the ratio between the signal level and the noise level of the response voice, and the voice response section outputs the response voice at the signal level and noise level determined by the control section. ing.
次に９図面を参照して本発明の詳細な説明する。 Next, the present invention will be described in detail with reference to nine drawings.
第１図は本発明の一実施例による音声認識応答装置を用
いたシステムのブロック図である。FIG. 1 is a block diagram of a system using a voice recognition response device according to an embodiment of the present invention.
第１図において、１は電話機、２は電話回線である。音
声認識応答装置１０は入力信号のＳ／Ｎ計算部６．制御
部４．音声応答部５．音声認識部６を含んでいる。In FIG. 1, 1 is a telephone and 2 is a telephone line. The voice recognition response device 10 includes an input signal S/N calculation section 6. Control unit 4. Voice response section 5. It includes a voice recognition section 6.
第２図は、上記実施例の具体的な動作例を示したフロー
チャートである。まず、ステップＳ１において発声され
た音声は電話機１と電話回線２を通り、音声認識応答装
置１０に入力する。FIG. 2 is a flowchart showing a specific example of the operation of the above embodiment. First, the voice uttered in step S1 passes through the telephone set 1 and the telephone line 2, and is input to the voice recognition response device 10.
入力信号のＳ／Ｎ計算部６では入力信号の信号レベルと
雑音レベルとのＳ／Ｎ比（以下、これを工１３Ｎとする
）を計算しくステップＳ２）。The input signal S/N calculation unit 6 calculates the S/N ratio (hereinafter referred to as step 13N) between the signal level of the input signal and the noise level (step S2).
さらに音声認識部６で音声認識処理を行う（ステップｓ
３）。次に、制御部４において発声者に次の発声を促す
文言を選択しくステップｓ４）。Furthermore, the voice recognition unit 6 performs voice recognition processing (step s
3). Next, the control unit 4 selects the wording that prompts the speaker to make the next utterance (step s4).
これを音声応答部５に出力する。制御部４は同時に、音
声応答部５の応答音声信号のＳ／Ｎ（以下、これをＯ８
Ｎとする）をｓ ／ Ｎ計算部６からの工ＳＮに応じて
決定しくステップＳ５）。This is output to the voice response section 5. At the same time, the control unit 4 controls the S/N (hereinafter referred to as O8) of the response audio signal of the audio response unit 5.
s/N) is determined according to the SN from the s/N calculating section 6 (step S5).
これを音声応答部５に出力する。例えば０８Ｎ−α・ｌ
５Ｎ（ただし、αは定数）である。音声応答部５は電話
回線２に制御部４で決定されたＯ８Ｎにて応答音声を出
力しくステップＳ６）。This is output to the voice response section 5. For example, 08N-α・l
5N (where α is a constant). The voice response section 5 outputs a response voice at O8N determined by the control section 4 to the telephone line 2 (step S6).
発声者に文言を知らせる。この時発声者が聞く６一
応答音声のＳ／Ｎは、前に自分自身が発声した声のＳ／
Ｎに比例している。そこで、この応答音声を聞いた発声
者は、たとえば応答音声のＳ／Ｎが低い場合には９周囲
雑音があるとか声が小さいと判断して自然に次には大き
な声で発声するか又は周囲雑音が入らないようにする。Inform the speaker of the sentence. At this time, the S/N of the 6-1 response voice that the speaker hears is the S/N of the voice that he/she uttered previously.
It is proportional to N. Therefore, when the speaker hears this response voice, for example, if the S/N of the response voice is low, he or she may decide that there is ambient noise or that the voice is low, and then naturally speak in a louder voice or Avoid noise.
