I'm writing Alexa skills and want to write a skill to store the speaker's words.
For example, if I say, 'Alexa, save {whatever I say}', it should save the words in some string.
Now from what I understand, the intent schema something should be like
{
intents:[
"intent" : "SaveIntent"
]
}
and utterances like
SaveIntent save
SaveIntent store
In this case, how do I store '{whatever I say}'?
To capture free-form speech input (rather than a defined list of possible values), you'll need to use the AMAZON.LITERAL slot type. The Amazon documentation for the Literal slot type describes a use case similar to yours, where a skill is created to take any phrase and post it to a Social Media site. This is done by creating a StatusUpdate intent:
{
"intents": [
{
"intent": "StatusUpdate",
"slots": [
{
"name": "UpdateText",
"type": "AMAZON.LITERAL"
}
]
}
]
}
Since it uses the AMAZON.LITERAL slot type, this intent will be able to capture any arbitrary phrase. However, to ensure that the speech engine will do a decent job of capturing real-world phrases, you need to provide a variety of example utterances that resemble the sorts of things you expect the user to say.
Given that in your described scenario, you're trying to capture very dynamic phrases, there's a couple things in the documentation you'll want to give extra consideration to:
If you are using the AMAZON.LITERAL type to collect free-form text with wide variations in the number of words that might be in the slot, note the following:
- Covering this full range (minimum, maximum, and all in between) will require a very large set of samples. Try to provide several hundred samples or more to address all the variations in slot value words as noted above.
- Keep the phrases within slots short enough that users can say the entire phrase without needing to pause.
Lengthy spoken input can lead to lower accuracy experiences, so avoid designing a spoken language interface that requires more than a few words for a slot value. A phrase that a user cannot speak without pausing is too long for a slot value.
That said, here's the example Sample Utterances from the documentation, again:
StatusUpdate post the update {arrived|UpdateText}
StatusUpdate post the update {dinner time|UpdateText}
StatusUpdate post the update {out at lunch|UpdateText}
...(more samples showing phrases with 4-10 words)
StatusUpdate post the update {going to stop by the grocery store this evening|UpdateText}
If you provide enough examples of different lengths to give an accurate picture of the range of expected user utterances, then your intent will be able to accurately capture dynamic phrases in real uses cases, which you can access in the UpdateText slot. Based on this, you should be able to implement an intent specific to your needs.
Literal deprecation? –
Ecclesiology Important: AMAZON.LITERAL is deprecated as of October 22, 2018. Older skills built with AMAZON.LITERAL do continue to work, but you must migrate away from AMAZON.LITERAL when you update those older skills, and for all new skills.
Instead of using AMAZON.LITERAL, you can use a custom slot to trick alexa into passing the free flow text into the backend.
You can use this configuration to do it:

Tetragram You can try using the slot type AMAZON.SearchQuery. So you intent would be something like this
{
"intents": [
{
"intent": "SaveIntent",
"slots": [
{
"name": "UpdateText",
"type": "AMAZON.SearchQuery"
}
]
}
]
}
as of end of 2018 I am using SearchQuery to get whatever the user says.
It does work, and I have it on production systems.
But you have to ask the user something and fill the slot.
For example:
query (choose whatever name you want)I want to watch {query} or {query} or I want {query}const message = 'What movie do you want to watch?'
handlerInput
.responseBuilder
.speak(message)
.reprompt(message)
.addElicitSlotDirective('query')
.getResponse();
Here is the better possible way to achieve what you were looking for. After trying several methods, I have got the complete words of the statement asked Alexa.
You need to make the following setup in your Alexa skill (name of intent, slot name, and slot type you can choose as per your need)
Setting up Intent
Setting up custom slot type
After setting up your Alexa skill, you can invoke your skill, keep some response for launch request and say anything you want, and you can catch the entire words or text as shown here.
"intent": {
"name": "sample",
"confirmationStatus": "NONE",
"slots": {
"sentence": {
"name": "sentence",
"value": "hello, how are you?",
"resolutions": {
"resolutionsPerAuthority": [
{
"authority": "xxxxxxx",
"status": {
"code": "xxxxxxx"
}
}
]
},
"confirmationStatus": "NONE",
"source": "USER"
}
}
}
Note*: In this method, you will need to handle utterances properly if there are more than one intent.
Updated: This answer isn't true. mentioned in the comments there is the Amazon.Literal Slot type that should allow this.
Alexa doesn't currently support access to the users raw speech input. It may be possible in the future, or you can look at some other voice to text API's such as Google's.
The only way to do this currently with Alexa would be to have a set list of words that the user could say that it would save.
To do that you can follow one of Amazon's examples of using a custom slot type. Then put all of the possible words that the user would say into that category.
AMAZON.Literal slot type, which will allow capturing freeform input. However, you have to provide it a variety of example inputs to train it as to what general sort of inputs to expect. –
Ecotone (8/5/17) Unfortunately this feature was removed from Amazon with the elimination of AMAZON.LITERALS.
However, depending on how interested you are in capturing free form inputs you may be satisfied with an input MODE that captures one word, name, city, number, letter, symbol, etc. at a time and strings them together into a single variable with no message in between.
I've worked on a password input mode that can be modified to collect and concatenate user inputs. While your input would be slower, if you optimize your lambda function you may be able to achieve a fast user experience for entering a few sentences. The structure is what's important. The code could easily be adapted.
