Problem:
You are developing a bilingual site and have a custom post type called 'portfolio'. While the taxonomy names display correctly in French, they appear in French instead of English on the English page, despite having translations set in WPML.
Solution:
First, ensure that you have translated the taxonomy slug or label via WPML > String Translation. Use the filter hook

wpml_translate_single_string

to retrieve the translated string. Here's how you can implement it:

$taxonomy_objects = get_object_taxonomies( 'post', 'objects' );
foreach ($taxonomy_objects as $taxonomy) {
    $tax_slug = apply_filters( 'wpml_translate_single_string', $taxonomy->name, 'WordPress', 'URL '. $taxonomy->name .' tax slug' );
 
    echo $tax_slug;
    echo "<br />";
}

For more details, follow this documentation: https://wpml.org/wpml-hook/wpml_translate_single_string
If you prefer using SQL queries, you can fetch the translated name directly from the database using the following query:

SELECT st.value AS translated_text
FROM wp_icl_strings s
JOIN wp_icl_string_translations st ON s.id = st.string_id
WHERE s.context = 'WordPress' -- string domain
  AND s.value = 'category'
  AND st.language = 'fr'
  AND st.status = 10; -- completed status

Please test this on your staging site before applying it to your production site.
