# Speech To Text (STT) This chapter describes how STT are working. This configuration must apply in the settings.yml. The syntax used is YAML. ## General defaults The setting.yml defines the STT you want to use by default ``` default_speech_to_text: "type default STT here" ``` Then, still in the settings.yml file, each STT must set up its configuration following 'speech_to_text' tag : ``` speech_to_text: - STT1: STT1parameter1: "value option1" STT1parameter2: "value option2" - STT2: STT2parameter1: "value option1" ``` ## Current Available STT ### Google The google STT is based on the [Google Speech Recognition API](https://cloud.google.com/speech/) | parameter| required | default | choices | comments | |----------|----------|---------|---------|----------| | key | No | None | | | | language | No | en-US | [lang](https://en.wikipedia.org/wiki/Google_Voice_Search#Supported_languages) |LCID string| ### Bing The Bing STT is based on the [Microsoft Bing Voice Recognition API](https://www.microsoft.com/cognitive-services/en-us/speech-api) | parameter| required | default | choices | comments | |----------|----------|---------|---------|----------| | key | YES | None | |User info | | language | No | en-US | [lang](https://www.microsoft.com/cognitive-services/en-us/speech-api)|7 languages| ### wit.ai The wit.ai STT is based on the Microsoft [Wit.ai API](https://wit.ai/) | parameter| required | default | choices | comments | |----------|----------|---------|---------|----------| | key | YES | None | |User info | | language | No | en-US |[lang](https://docs.api.ai/docs/languages)| | ### api.ai The api.ai STT is based on the [api.ai API](https://api.ai/) | parameter| required | default | choices | comments | |----------|----------|---------|---------|----------| | key | YES | None | |User info | | language | No | en-US |[lang](https://docs.api.ai/docs/languages)| | ### Houndify Not working yet ... in coming | parameter| required | default | choices | comments | |----------|----------|---------|---------|----------| | key | YES | None | |User info | | client_id| YES | None | |User info | | language | No | en-US | en-US | | ## Full Example In the settings.yml file : ``` default_speech_to_text: "google" speech_to_text: - google: language: "fr-FR" - wit: key: "B5JI3YUSLYOYWNIZRNBVM34XUODME2K" - bing: key: "9e48dert65904838bedc11aea6b36fb0" - apiai: key: "e0cbff145af44944a6b9f82c0668b527" language: "fr" - houndify: key: "6ej90T7qAV74OYXk4X4vI2Xhk7wPsJu4aEZ0G5Ll-BMmV1JGtFpCxtSH9SmTY4G3bpEJ7a5y_GTQid-CAKI6vw==" client_id: "lM2JXeaSticbSo9-llczbA==" ```
