Phonetic matching percentage of precision

i already configured phonetic matching on my Elastich search index, and it is working fine, but how i can know the percentage of precision.
for example when i run any query like the below, i will get the result ordered by score, but still i will not be able to know if it is really matching my query 80% or above for example.
GET apartmentmasterdata/doc/_search
"query": {
"match": {
"building.phonetic": {
"query": "building name",
"operator": "or"
